07-13 BMW M3 (E9X) Race-Spec Oil Cooler - 8025

The CSF 8025 Race-Spec Oil Cooler is a true performance upgrade for the E9X M3, engineered to deliver increased cooling capacity and long-term reliability under hard street or track use. Developed in collaboration with VF Engineering, this cooler is designed as a true drop-in replacement that installs without modification and retains OEM-style fitment.

Unlike the factory cooler’s mechanically joined construction, the CSF unit features a fully TIG-welded, cast end-tank design for superior durability. The tapered cast end tanks are shaped to match the OEM bumper contour for clean, factory-like packaging—without interfering with aftermarket splitter fitment.

Important Oil Line Note (Early vs. Late Production)

For vehicles built on or before 03/2008, BMW superseded the oil lines and the earlier lines are physically different. The CSF 8025 is designed for later-spec oil lines. If your car has early lines, you may need to update them.
