VAC Recommends that you replace your spark plugs in these turbo engines based on how heavily modified your engine is... typically every 40k is wise, but as soon as every 20k if your running big turbos and high boost levels daily.

Direct replacement plugs for N54 engines as well as other late model BMWs.

NGK D7EA Spark Plugs, BMW S14/S38
Buy Now: ~~$8.38~~ $4.95

VAC Recommends that you replace your spark plugs in these Classic 'M' engines every 15-20k miles, depending on use.

Direct replacement plugs for the S14 and S38 found in E30 M3, E28 M5, E24 M6.

Also used in some BMW motorcycle models.

Tech Notes:

- We recommend these plugs for many s14 engines up to about 250BHP depending on your fuel used and ignition timing.
- For max performance street and mild race engines, up to about 310BHP, we recommend a race plug like the Bosch XR4CS

NGK OE Replacement Spark Plugs, BMW M50/M52/S50/S52

NGK OE Replacement Spark Plugs, BMW M50/M52/S50/S52
Buy Now: ~~$11.69~~ $7.95

From our experience, the VAC techs recommend these specific resistor type NGK Spark plugs for M50, M52 and S50us / S52us that are stock, or mildly modified with bolt ons.
The heat range of a plug should be matched to the engines used to ensure proper spark plug thermal performance. If the heat range is not optimal, then fouling of the plug or at the other end of the spectrum- detonation can occur.
The optimal firing-end temp is approximately between 930°F and 1475°F and if the temperature varies too high or low from these temps carbon fouling or plug over heating (and possibly plug failure or pre-ignition) can be the result.

In our testing and years of use, these factory original replacement type plugs work excellent on both stock and lightly modified engines.
Despite the claims of other "fancy" types of plugs, these have shown the best performance on the Dyno as well as a smoother idle and plenty of lifespan.

Under hard performance driving conditions, checking spark plug gap and/or replacing these plugs on a regular 25-35k mile intervals is recommended for best results.

We always keep these in stock for whenever you need them!

After a lot of testing and years of racing and street driving, VAC continues to recommend the following proven spark plugs for the S54:

Priced individually (1), Please order as many as needed for your engine.

385HP or less:Despite the claims of other "fancy" types of plugs, the OEM type plug show the best performance on the Dyno over the life of the plug and tend to also be the most reliable. OEM NGK Spark Plugs, BMW Part(12 12 0 022 902) for the S54.
Can't argue with good hard data; so we sell and recommend these that work the best.
Suitable for all naturally aspirated cars under 400HP. For highly modded engines, or forced induction cars; see the plugs we recommend below.

390HP or more NA / 500HP+ Boosted: The VAC staff recommends these specific OEM-manufactured spark plugs for replacements on S54s that are boosted, have been fitted nitrous, or increased compression.
They are of a lower heat temperature than standard units, making them a better choice for modified engines that see forced induction or internal upgrades.
In our testing and years of use, these plugs work excellent on each engine application they are intended for.

Despite the claims of other "fancy" aftermarket types of plugs, these have shown the best performance on the Dyno as well as a smoother idle and plenty of lifespan.

Under hard performance driving conditions, checking spark plug gap and/or replacing these plugs on a regular 25-35k mile intervals is recommended for best results.

NGK Spark Plugs for Modified Engines, BMW M50/M52/S50/S52
Buy Now: ~~$11.69~~ $7.95

From our experience, the VAC techs recommend these specific resistor type NGK Spark plugs for M50, M52 and S50us / S52us that are boosted or have bolt on mods over other types of plugs...

The heat range of a plug should be matched to the engines used to ensure proper spark plug thermal performance.In our testing and years of use, these plugs work excellent on both lightly modified and engines running boost up to 16lbs.

Despite the claims of other "fancy" types of plugs, these have shown the best performance on the Dyno as well as a smoother idle and plenty of lifespan.

Under hard performance driving conditions, and or boost- checking spark plug gap and/or replacing these plugs on a regular 20-35k mile intervals is recommended for best results.

We always keep these in stock for whenever you need them!

Plug shown in images is for example only, it is of the OE plug

VAC Tech Tips:
-These plugs work well for bolt on turbo charged M5x/S5X and many supercharge apps.
-These plugs are 1 heat range colder than 96-99 OEM specs
-Gap is .32 stock, you may set gap at .28 for best results with higher boost levels

Why these plugs?
If the heat range of your plug is not optimal, then fouling of the plug or at the other end of the spectrum- pre ignition / detonation can occur. Very problematic on modified applications.
Optimal firing-tip temp is obtained between an approximately between 930°F and 1475°F and if the temperature varies too high or low from these temps, carbon fouling or plug over heating (and possibly plug failure or engine internal damage) can be the result.
While they sound non-exotic, most often copper plugs with a nickel plating are an excellent choice for this application. Their thermal/electrical conductivity is excellent, and copper has the ability to dissipate the heat after firing very efficiently. Some may recommend Silver plugs and while it's an excellent material to produce a strong spark with very good thermal conductivity, It's downside is it's soft and subject to more rapid deterioration.
That brings up exotic metals, introduced mostly to extend spark plug life. Iridium and Platinum plugs often have a small tip, and while they have a long lifespan, they have their own issues, one of which is the small tip over heating and leading to a tendency for pre-ignition under very high loads (peak boost at high RPMS for example). When the plugs must operate over a wide temperature range fine tip electrode plugs can sometimes be more problematic to dyno tune.
Its for these reasons these seemingly simple and inexpensive plugs work very well.
