Product Description

The CSF 8266 High-Performance Engine Oil Cooler is a direct-fit upgrade designed specifically for BMW's S58 3.0L turbocharged inline-6 engines on G8X platform vehicles including the M2, M3, M3 Competition (and xDrive), M4, and M4 CSL from 2021 through 2025. Featuring advanced CSF AC condenser technology and a 1-row, 32 mm 10-channel microtube core with tall multi-louvered fins, this cooler increases oil-flow efficiency and surface heat rejection compared to the OEM unit, helping keep oil temperatures under control during spirited driving, track use, or high-load conditions.

Built for durable performance and easy installation, the CSF 8266 reuses factory mounting points, OEM rubber seals, and ducting for a straightforward, drop-in fit with no chassis modifications required. A rugged rock guard helps protect the cooler from debris, while precision engineering ensures consistent thermal management under extreme use. Backed by a 2-year limited warranty, this oil cooler is ideal for enthusiasts who push the limits of performance on road and track alike.
