CSF BMW S58 M2/M3/M4 (G87/G80/G81/G82/G83) Engine Oil Cooler

The factory oil cooler on the S58 does a genuinely decent job in stock form - but once you start adding power and pushing the car in aggressive driving conditions, its limitations quickly show. With many motorsport teams and race enthusiasts now pushing well over 800 horsepower, S58 oil temperatures are climbing well above normal, and once they pass a safe limit, the G8X goes into limp mode - enough to ruin a race, track session, or your overall driving fun.

CSF's High-Performance Engine Oil Cooler was designed to deliver the best possible performance while keeping genuinely factory-like fitment. This is a truly unique design using CSF's AC condenser technology: a 1-row, super-high-pressure 32mm, 10-channel microtube provides optimal oil flow and maximum surface area contact, paired with 8mm tall multi-louvered fins - noticeably taller than the OEM's 6mm fins for improved airflow efficiency. By keeping the factory mounting location and relative dimensions, the factory ducting and shrouds are all reused with no modifications necessary. A rock guard is included as standard, addressing the well-documented risk of OEM coolers being punctured by road debris and spilling oil mid-drive or mid-race.

Works with: OEM inlet/outlet connections, ducting, and shrouds - true drop-in fit, no modification required.
