'''Problem:''' You need to be replacing your sparking stoppers, but you don't know which ones to buy. You searched for the answer. Honest.

'''Cause:''' You used poor search terms and came up with threads about sunroof maintenance

'''Solution:''' Look at the following information and then post a thread about how it is confusing.

We're not covering glow plugs.

Spark plugs vary from model to model, so just because you see that someone uses a certain plug in their car, it doesn't necessarily mean that you would use that same plug in your own car. Hopefully, the following information will help you choose the right flicker corks for your E28.

<nowiki>***</nowiki>A very important note: If you take the information you find here to one of your local discount auto parts suppliers, you will more than likely be offered a set of Platinum plugs. The sales person will probably share some story about how the spark plug rescued his or her dog/father/mother/aunt/baby daddy/hair stylist from an untimely death in a swimming pool underneath a fiery dragon's lair. None of that will have ever actually happened. Platinum plugs will cause running issues with M10, M20 and M30 motors, so they are to be avoided.

<nowiki>**</nowiki>A not-so important note: The motors sent to the budding North American market in the '80s were designed to run Silver electrode spark plugs. If you cannot find spark plugs with silver electrodes, copper plugs are a suitable substitute.

'''Here's how a spark plug works''' (and you thought I'd just spoon-feed you which ones to buy for your Eta )''':'''

Spark plugs are simply insulated plugs that are threaded into the cylinder head to ignite the air/fuel mixture in the combustion chamber of an internal combustion engine. Simple, yes, but...

They also have another use. They transfer heat out of the combustion chamber. The amount transferred out is dependent upon the length of the insulator, and the materials of which they're made from. You might have heard the terms 'hot' or 'cold' referring to plugs. Those generally refer to the heat ranges, which are determined by the size of the insulator. Colder plugs have smaller insulators, which allows more heat to leave the combustion chamber. Hotter plugs are the opposite. Colder plugs are generally used in high power motors since heat dissipation is key to preventing pre-ignition (also known as pinging or knocking). Hotter plugs can keep the combustion chambers cleaner (burning off carbon deposits, etc) and more efficient by keeping temperatures more even. Lower compression motors are not as susceptible to pre-ignition, so they will more than likely run a hotter plug.

Hopefully that was enough information to give you a basic understanding, but not enough info to keep you from being confused.

'''How do you know if you need plugs?'''

Great question. Spark plugs should be changed every Inspection II service, or roughly 50,000 miles. I'll change mine a bit earlier than that, but when you do a valve adjustment, you can inspect your spark plugs.

Thank you to the Haynes manual folks for giving us this great color chart to "read" spark plugs:

'''I am an E28 owner and need plugs. What kind of plugs should I buy?'''

That's a fantastic question. There were several different motors offered in the E28 across the globe, and they don't all use the same plug! These are the plugs originally specified for these applications. Some of the plugs might not be in production any longer, so be careful when purchasing. Using the links below on how to decipher the part numbers, you can find a suitable plug for your motor.

Let's start with the US stuff:

* 528e M20B27 up to 12/1986: Bosch WR9LS
* 528e M20B27 12/1986 on: Bosch W8LCR
* 533i M30B32 up to 1/84: Bosch WR9DS
* 533i M30B32 1/84 on: Bosch WR9LS
* 535i M30B34 all: Bosch WR9LS
* M5 S38B35 all: Bosch X5DC

And the Euro stuff:

* 518 M10B18 all: Bosch W8DC
* 518i M10B18 all: Bosch W8DC
* 520i M20B20 all: Bosch W8DC
* 525e M20B27 all no catalyst: Bosch W8DC
* 525e M20B27 up to 12/86 with catalyst: Bosch W9LC
* 525e M20B27 from 12/86 with catalyst: Bosch W8LCR
* 525i M30B25 all: Bosch W8DC
* 528i M30B28 all: Bosch W8DC
* 535i M30B34 no catalyst: Bosch W8DC
* 535i M30B34 with catalyst: Bosch W9DC
* M5 M88B35 all: Bosch X5DC

I only decided to cover the motors originally included in E28s, but for the E28 community here in the United States, there's a rather common motor swap. The M30B35 from '88-89 E24 635s, E32 735s and E34 535s. These are not the same as the M30B34 used in the E28 535i, and therefore use a different plug. The Bosch W8LCR.

You are not restricted to Bosch plugs. Many people run NGK plugs with good results. Remember, when cross-referencing that NGK heat range codes are the inverse of Bosch. A Bosch 9 is an NGK 4.

Here is some fun info:

I hope you found this useful. Thanks.

The '''BMW E28''' is the second generation of [[wikipedia:BMW_5_Series|BMW 5 Series]] executive cars, which was produced from 1981 to 1988 and replaced the [[wikipedia:BMW_5_Series_(E12)|E12 5 Series]]. Pre-series production began in April 1981 and the car was introduced in the autumn that year.

The E28 was initially produced with straight-four and straight-six petrol engines until 1983, when the 524td model became the first BMW car to be powered by a diesel engine. It was also the first 5 Series with the center console angled towards the driver and to be available with anti-lock brakes (ABS).

The first [[BMW M5#E28|BMW M5]] was produced during the E28 generation. It was powered by the [[BMW M88|M88/3]] and [[BMW S38|S38]] straight-six engines. The [[BMW 6 Series (E24)|E24 6 Series]] coupés were built on the E28 platform from 1982 to 1989.

The E28 was replaced by the [[BMW 5 Series (E34)|E34 5 Series]] in 1988.

== Body and interior ==
The E28 has a self-supporting body that is welded to the body platform. The passenger cell is a safety passenger cell with deformation elements both in the front and rear of the vehicle. Unlike its E12 predecessor and E34 successor, the E28 has a rear-hinged bonnet. The boot has a volume of {{convert|460|litre|gal|0|abbr=on}}. Most models have a fuel tank capacity of {{convert|70|litre|gal|0|abbr=on}},<ref name="BMW-E28-Betriebsanleitung" /> with some models having a smaller tank of {{convert|63|litre|gal|0|}}. The kerb weight is {{convert|1140|–|1410|kg|lb|0|abbr=on}}.<ref>{{cite web|title=BMW E28 5 Series 518i Specs|url=https://www.ultimatespecs.com/car-specs/BMW/1360/BMW--518i.html|website=www.ultimatespecs.com|access-date=13 May 2017}}</ref>

Cruise control, an on-board computer (to display trip information), and a "check control" panel (to alert the driver about fluid levels and lighting faults) were introduced to the 5 Series on the E28. The glazing is made of single-pane safety glass, the windscreen has laminated glass.<ref name="BMW-E28-Betriebsanleitung" /> As part of developing the air-conditioning system for the E28, several of the BMW engineers in charge of this program drove a previous generation E12 5 Series during the middle of summer in Texas. The E12 528i was painted black with a black interior, and driven {{convert|500|mi|km|0|abbr=on}} in one day.<ref name=OBC86>{{citation | ref = RT86 | title = Road & Track On BMW Cars 1979-1983 | date = 1986 | publisher = CBS Publications | location = Greenwich, CT | page = 56 }}</ref>

The styling was developed under BMW's chief designer [[Claus Luthe]],<ref>{{cite book |last1=Caspers |first1=Markus |title=Designing Motion: Automotive Designers 1890 to 1990 |date=2017 |publisher=Birkhäuser |isbn=9783035607840 |page=134 |url=https://books.google.com/books?id=B9UXDQAAQBAJ&pg=PA134 |access-date=18 June 2018 |language=en}}</ref> with development of the E28 beginning in 1975.<ref>{{cite web |title=BMW Classic - Recherche-Client |url=https://bmw-grouparchiv.de/research/detail/index.xhtml?id=3824021 |website=bmw-grouparchiv.de |access-date=22 November 2019 |language=de}}</ref> At the time that BMW was designing the E28, the company had only one computer, which was used for payroll management and spare parts logistics. Wolfgang Matschinsky and his team borrowed that computer to perform the calculations necessary to develop the new drivetrain and chassis. This was due to the fact that the addition of an ABS system necessitated a redesign from the previous model due to excessive vibrations under heavy braking.<ref>{{Citation|title=The BMW 5 Series History.

== Engines ==
The E28 was the first 5 Series produced with diesel engines (the 524d and 524td models) and with a petrol engined model specifically aimed at increased fuel economy (525e/528e model).

The four models available at the launch of the E28 were the 518, 520i, 525i and 528i,<ref>BMW: [https://bmw-grouparchiv.de/research/media/cdd55d90-1cc5-4456-a984-4ef3b84ad22e/web 518 520i 525i 528i]. February 1982</ref> with the 518 using a straight-four petrol engine and the other three models using a straight-six petrol engine. Over the course of the E28 model, the following models were added: the 524d and 524td using diesel engines, the 518i (a fuel-injected version of the 518), the 525e/528e as fuel-economy models, and the upper-specification 533i, 535i, M535i, and M5 models.

A liquid petroleum gas (LPG) option was introduced for some petrol engines in 1984.<ref>{{cite web |title=5er BMW mit Autogasanlage |url=https://bmw-grouparchiv.de/research/detail/index.xhtml?id=6628055 |website=bmw-grouparchiv.de |access-date=22 November 2019 |language=de}}</ref>

'''M535i:''' The top of the regular production model range, the M535i uses the drivetrain from the 535i plus M-Technic suspension, and wheels and body panels not found on any other E28. The M535i was assembled on the standard E28 assembly lines in Dingolfing and Rosslyn. Factory performance figures for the manual transmission cars without a catalytic converter are a top speed of {{convert|230|km/h|mph|0|abbr=on}} and 0–100 km/h acceleration in 7.2 seconds. With a catalytic converter, the figures are a top speed of {{convert|217|km/h|mph|0|abbr=on}} and 0–100 km/h acceleration in 7.9 seconds<ref name="BMW-E28-Betriebsanleitung" />

== Drivetrain ==
BMW offered the E28 with both manual and automatic gearboxes. The torque is transmitted from the engine with a single-disc dry clutch with a torsional damper in the models with a manual gearbox, the automatic models have a torque converter with built in lockup-clutch.<ref name="BMW-E28-Betriebsanleitung" />

;Manual transmissions
The 5-speed manual transmissions are:<ref>{{cite web|title=5' E28 model selection|url=http://www.realoem.com/bmw/en/select?product=P&archive=1&series=E28&body=Lim|website=www.realoem.com}}</ref>
* [[Getrag]] 242 (for M10 and M20 engine models)
* Getrag 262 (M30 engines)

The 5-speed manual transmissions are:
* Getrag 240 (M10 and M21 engines)
* Getrag 245 (M10 engines)
* [[Getrag 260 transmission|Getrag 260]] (M20, M21 and M30 engines)

* Getrag 280 (M88/3 and S38 engines)
* [[List of ZF transmissions|ZF]] S5-16 (M20 engines)

;Automatic transmissions

* [[ZF 4HP22 transmission|ZF 4HP22]] EH (M20, M30)

== Suspension ==
Independent front and rear suspension is used, with [[Macpherson strut]]s at the front and a [[trailing arm#Semi-trailing arm|semi-trailing arm]] design for the rear.<ref name="BMW-E28-Betriebsanleitung">{{citation|publisher=BMW AG |title=Betriebsanleitung, Serviceheft 518, 520i, 525e, 525i, 528i, 535i, M535i, 524td |date=1985 |language=de |url=https://bmw-grouparchiv.de/research/detail/index.xhtml?id=3058985 |access-date=20 February 2017}}</ref>

The front suspension was upgraded to use dual links at the bottom of the strut, as first seen on the [[BMW 7 Series (E23)|E23 7 Series]]. This increases steering offset while cornering, to improve steering feel.<ref name="noakes">{{cite book|last1=Noakes|first1=Andrew|title=The Ultimate History of BMW|date=2008}}</ref>{{refpage|page=106}} Double-acting shock absorbers, coil springs and a front [[anti-roll bar]] are used.

The rear suspension is mounted on a delta beam that is connected to the body with three screws in rubber bearings, that have longitudinal play.{{citation needed|date=November 2017}} Some models have a rear anti-roll bar.<ref name="BMW-E28-Betriebsanleitung" />

The steering on most models is a speed-dependent [[recirculating ball]] power steering system made by ZF Friedrichshafen. The 518i has a Gemmer steering system with a double enveloping worm gear, also made by ZF.<ref name="BMW-E28-Betriebsanleitung" />

Wheel sizes are 14-inch (16-inch for the M5 model) or 390 mm [[Michelin TRX]].<ref>{{cite book|last1=Taylor|first1=James|title=BMW M5- The Complete Story|date=2015}}</ref>{{refpage|page=44}}<ref>{{cite web|title=1981 BMW E28 5 Series 525i Specs|url=http://www.ultimatespecs.com/car-specs/BMW/230/BMW-E28-5-Series-525i.html|website=www.ultimatespecs.com|access-date=21 November 2017}}</ref><ref>{{cite web|title=1984 BMW E28 5 Series 535i Specs|url=http://www.ultimatespecs.com/car-specs/BMW/1409/BMW-E28-5-Series-535i.html|website=www.ultimatespecs.com|access-date=21 November 2017}}</ref> All rims have 22 mm positive rim offset.<ref name="BMW-E28-Betriebsanleitung" />

== Brakes ==
The brakes use a hydraulic dual-circuit brake system with power assistance. The front wheels have disc brakes, that are – except for the 518i – internally ventilated. All models with 2.5 L or more displacement have rear disc brakes (non-vented), while the lesser powered models have rear drum brakes. To prevent the wheels from locking, BMW equipped the E28 after 1984 with an [[anti-lock braking system]], although it was an option in some markets.<ref name="BMW-E28-Betriebsanleitung" />

== M5 model ==
[[File:BMW M5 E28 Minervablau.jpg|thumb|right|M5 model]]
{{main|BMW M5#E28 M5 (1984–1988)}}
The E28 was the first M5 model produced, and is powered by the [[BMW M88|M88/3]] and [[BMW S38|S38]] straight-six engines.

== North American market models ==
[[File:BMW-535is.jpg|thumb|right|BMW 535is (North America)]]
[[File:M5sig (E28).jpg|thumb|North American M5 fitted with European market headlights]]
The North American line-up consisted of the '''528e''' (1982–1988, known as the 525e in Europe), '''533i''' (1983–1984), '''535i''' (1985–1988), '''524td''' (1985–1986), '''M5''' (1986–1987) and '''535is''' (1987–1988).

The launch model was the 528e in 1982, followed by the 533i.<ref>{{cite web|title=1984 BMW 533i E28 Specifications|url=http://www.carfolio.com/specifications/models/car/?car=227689|website=www.carfolio.com|access-date=22 November 2017}}</ref> The optional automatic transmission was initially a 3-speed (a 4-speed automatic was available in Europe at the time), with a 4-speed automatic transmission becoming optional in 1983. From 1985, all North American models had ABS Brakes as standard.

The North American E28 models had larger bumpers (designed to withstand a {{convert|5|mph|abbr=on}} collision without body damage), which increased the overall length by {{convert|180|mm|in|1|abbr=on}}.{{citation needed|date=May 2019}}

The 528i, 533i and 535i were sold with a [[catalytic converter]] in the United States.

Instead of importing the M535i, BMW of North America created the 535is.<ref>{{cite web|title=1985 BMW E28 5 Series 535is (US) Specs|url=http://www.ultimatespecs.com/car-specs/BMW/1413/BMW-E28-5-Series-535is-(US).html|website=www.ultimatespecs.com|access-date=22 November 2017}}</ref> This model is based on a 535i, plus front and rear spoilers, sport suspension and sport seats.

Production of North American market M5 models began in late 1986 (two years after M5 production began for European markets), and it was only produced for twelve months as 1988 [[model year]] car.<ref>{{cite web|title=1988 BMW M5 values|url=https://www.hagerty.com/apps/ValuationTools/1988-BMW-M5|website=www.hagerty.com|access-date=24 October 2017}}</ref> North American M5 models use the S38 engine instead of the M88/3.<ref>{{cite book|last1=Taylor|first1=James|title=BMW M5 - The Complete Story|date=2015|isbn=978-1-78500-045-4}}</ref>{{refpage|page=37}} All North American M5 cars were painted Jet Black and most interiors were tan ("Natur") coloured leather.<ref>{{cite web|title=FAQ E28 M5|url=https://www.bmwmregistry.com/model_faq.php?id=7|website=www.bmwmregistry.com|access-date=24 October 2017}}</ref>

== Production ==
E28 production started in July 1981 and ended in December 1987.<ref>{{cite book|last1=Taylor|first1=James|title=BMW M5: The Complete Story|date=February 2016|publisher=The Crowood Press UK|location=Ramsbury, Marlborough Wiltshire|isbn=978-1785000461|url=https://books.google.com/books?isbn=1785000462|access-date=20 March 2017}}</ref> A total of 722,328 cars were built.<ref name=DeAutos45bis90Oswald>{{cite book |last=Oswald |first=Werner |title= Deutsche Autos 1945–1990, Band 4, 1. Auflage|year=2001 |publisher=Motorbuch Verlag |location=Stuttgart |isbn=3-613-02131-5}}</ref>

The E28 was still sold in North America as a 1988 Model Year car after its E34 successor had been released in Europe in early 1988. A limited edition model was also sold in South Africa from mid-1987 to the end of 1988.<ref>{{cite web|title=M5 E28|url=http://www.africanmusclecars.com/index.php/bmw/m5-e28|website=www.africanmusclecars.com|access-date=16 December 2013}}</ref>
