Cheap BMW 8 Series Oil Cooler

Yes, oil coolers are fitted across the BMW 8 Series range, though the exact type and configuration varies by engine. The high-performance petrol and diesel engines in the 8 Series all benefit from oil cooling given the power outputs involved. When searching for a used unit, make sure you're matching by engine code rather than just the model name, as different engines use different cooler designs.

The modern BMW 8 Series (G15 coupe, G14 convertible, G16 Gran Coupe) launched in 2018 after a long gap since the original E31 8 Series which ran from 1990 to 1999 — these two generations share no parts whatsoever. Within the current G-series range, a mid-cycle refresh arrived around 2022, which may have brought changes to ancillary components and mountings; confirm with the breaker whether a pre-2022 oil cooler crosses that boundary against your specific registration. The E31 and G-series are completely distinct platforms, so only search within your own generation.

Both years sit within the same G-series generation and share the B57 diesel engine code, which is the most important factor for oil cooler fitment. In many cases these will be compatible, but ancillary bracket and pipe configurations can change at any point in a production run without a formal facelift, so confirm with the breaker against your full registration before buying. Always supply your engine code from your V5 or a VIN check when requesting a quote.

Engine code matters above everything else for mechanical parts like oil coolers — a 2019 840i (petrol, B58 engine) and a 2019 840d (diesel, B57 engine) will use different oil coolers despite being the same year and badge. The M850i uses the N63 V8, which is different again, and the M8 uses a high-output version of that engine with its own specification. Pull your engine code from your V5 logbook or a free VIN check and supply it to the breaker when requesting a quote.

Trim level does not affect oil cooler fitment — M Sport, Sport, and base-specification 8 Series cars with the same engine code use the same oil cooler. M Sport is a cosmetic and suspension package, not a mechanical engine variant, so it makes no difference to this part. The distinction that does matter is the full M models (M8, M8 Competition), which use a different high-output engine specification and will require their own oil cooler — confirm against your engine code with the breaker.

No — the E31 8 Series and the current G-series 8 Series are entirely different vehicles built roughly two decades apart, with different engines, cooling systems, and plumbing. There is no parts compatibility between the two generations for any mechanical components including the oil cooler. Make sure any quotes you receive are specific to your generation and engine code.
