Updated Oil Cooler Pipe Set for BMW E90 E92 E93 M3 S65 - Part Number E9XM3-SUP-PIPES

Planning a CSF-8025 front oil cooler on your E9X M3 V8 and want a straight, leak-free install? This later-spec hose assembly and fresh seals are the exact plumbing you need to mate the cooler to the car on early-build models. It replaces the original early pipework with the revised design so your cooler upgrade goes on cleanly, seals properly and performs as intended on road or track.

Who needs this conversion set

Pre 03-2008 E90, E92 and E93 M3 models left the factory with an earlier hose geometry that does not align with the CSF-8025 core. Converting to the updated BMW feed and return pipes with new O-rings solves the mismatch and prevents weeping or poor sealing. If your car still has the older lines, this is the proven retrofit for a correct CSF-8025 installation.
