Airtec’s ATMSBMW40 oil cooler kit is built for G80, G82 and G87 chassis running the S58 engine - no N54/N55 confusion, no F80/F82 guesswork. This isn’t an OEM replacement; it’s a purpose-built stage 2 upgrade for fast road, track day or daily driver use where oil temps climb past 115°C.
Direct-fit to G80 M3, G82 M4 and G87 M2 - uses factory mounting points, retains stock hoses and ducting
4.5L capacity (vs OEM 2.68L) + 18.5% core surface area - measurable delta on long laps or spirited A-road runs
Black powder-coated aluminium core, TIG-welded tanks, stainless steel brackets - built for repeated heat cycling, not showroom polish
Fits with stock airbox, front bumper and undertray - no trimming, no fabrication, no decat required
