Cheap BMW M3 Intercooler

Only some generations of the M3 have an intercooler, because not all of them used a turbocharged engine. The E46, E36, and E30 M3s all used naturally aspirated engines and have no intercooler whatsoever. From the F80 generation (2014–2018) onwards, the M3 gained a twin-turbocharged S55 engine and does use an intercooler, as does the G80 (2021–present) with its S58 engine. If you own an older naturally aspirated M3, you will not find an intercooler on your car and may be thinking of a different part.

All F80 M3s share the same S55 twin-turbo engine, so intercoolers from anywhere within the 2014–2018 production run are generally based on the same core unit. However, mounting brackets, pipework connections, and ancillary fittings can change mid-production without a formal facelift, so confirm with the breaker against your exact registration before buying. Supplying your engine code from your V5 or a VIN check gives the breaker the most reliable basis for matching the part.

The F80 (2014–2018) uses the S55 engine and the G80 (2021–present) uses the S58 engine — these are different units with different turbo and cooling layouts, so the intercoolers are not the same part. Attempting to cross these generations is very unlikely to result in a direct fit and is not something we would recommend assuming without specialist confirmation. Stick to sourcing an intercooler from the same generation and engine code as your own car.

Within the F80 generation, both the standard M3 and the M3 Competition use the same S55 twin-turbo engine, so the intercooler itself is mechanically the same part. Trim level does not affect intercooler fitment — the Competition package changes suspension settings, exhaust tuning, and interior specification rather than the core cooling hardware. That said, if any running changes were made to cooling components during production, confirm with the breaker against your registration to be certain.

The E90-generation M3 (2008–2013) used the naturally aspirated V8 S65 engine, which has no turbocharger and therefore no intercooler. If your car is overheating or you are chasing a cooling issue, the part you are more likely looking for is a radiator, oil cooler, or coolant hose rather than an intercooler. A breaker or specialist can help you identify the correct cooling component once you describe the symptom.

No — the intercooler is part of the engine's forced induction and cooling system and is not affected by body style. The S55 engine sits in the same basic location regardless of whether the car is a saloon or coupe, so body style is not a fitment consideration for this part. What matters is the engine code, which you can confirm from your V5 or a VIN check, and supplying that to the breaker will give them everything they need to match the correct unit.
