Dinan High Capacity Oil Cooler System for BMW E90 335i — cars with factory oil cooler and M‑Technic/M Sport bumper

The ultimate BMW E90 335i oil cooler upgrade. The Dinan High Capacity Oil Cooler System is a proven, bolt-on performance cooling solution for the E90 335i with a factory oil cooler and M‑Technic/M Sport bumper.

We use this kit on our own cars and customer builds, and feedback has been overwhelmingly positive. Customers report noticeably lower operating temperatures and greater confidence on fast road and track without compromise to daily drivability.
