Choosing the right used BMW M3 inlet manifold
Used inlet manifolds vary between vehicles - and whether you call it used, second hand or a replacement, matching the right one matters. These are the details breakers need to match the right part to your car - our request form asks them so you only hear from suppliers with the correct part:
- State whether it's petrol or diesel
- State the engine code if known

Fitment questions
Does a BMW M3 inlet manifold from an E46 M3 fit an E36 M3?
No — the E36 M3 (1992–1999) and E46 M3 (2000–2006) use entirely different engines, the S50/S52 family and the S54 respectively, and their inlet manifolds are not interchangeable. Always match the manifold to the engine code, not just the M3 badge. Confirm exact fitment with the breaker against your registration.
Will an inlet manifold from a 2002 E46 M3 fit a 2005 E46 M3?
Both years sit within the E46 M3 generation (2000–2006) and share the S54B32 engine code, so the core manifold is the same unit. However, there were minor ancillary and mounting changes during the E46 M3's production run, so confirm with the breaker against your registration before buying to make sure brackets and vacuum connections align.
Does the BMW M3 even have an inlet manifold — I thought only naturally aspirated engines had them?
All BMW M3 variants have an inlet manifold regardless of whether the engine is naturally aspirated or turbocharged — it is the plenum that distributes air to the cylinders and exists on every variant. Earlier M3s such as the E36 and E46 are naturally aspirated (S50, S52, S54), while later generations such as the F80 M3 (2014–2018) use the turbocharged S55 engine, but all of them carry an inlet manifold.
Does the gearbox type — manual or DCT — affect which inlet manifold I need for an F80 M3?
No, the inlet manifold is determined by the engine, and all F80 M3s (2014–2018) use the S55B30 engine regardless of whether the car has the six-speed manual or seven-speed DCT gearbox. You can safely source a manifold from an F80 M3 of either gearbox type.
I have an E90 M3 — will an inlet manifold from an E92 or E93 M3 fit mine?
The E90 saloon, E92 coupe, and E93 convertible M3s are all part of the same fourth-generation M3 (2007–2013) and share the S65B40 V8 engine code, so the inlet manifold is the same across those body styles. Body style does not affect fitment here — match on the engine code and confirm with the breaker against your registration.
Does it matter whether I buy an inlet manifold from a Competition Pack M3 or a standard M3?
The Competition Pack on the M3 is a suspension and wheel upgrade, not an engine modification, so the inlet manifold is identical to that on a standard M3 of the same generation and engine code. Trim level does not affect this part — focus on matching the engine code, which you can find on your V5 or via a VIN check, and confirm with the breaker against your registration.
