Dinan High Capacity Oil Cooler System – BMW E90 335i 2007–2008 (vehicles with factory oil cooler)
Keep your BMW 335i E90 running cool and consistent with the Dinan High Capacity Oil Cooler System. The N54 twin turbo engine is known to run hot, especially on fast road driving, track days and tuned cars. Elevated oil temperatures lead to heat soak and that dreaded limp mode. This Dinan oil cooler upgrade is engineered to significantly reduce oil temps and stabilise performance, giving you reliable power lap after lap and mile after mile.
Why upgrade your BMW 335i oil cooler
- BMW 335i E90 oil cooler upgrade for lower oil temperatures and improved reliability
- Ideal for spirited driving, track days and performance builds where increased boost generates more heat
- Helps prevent heat soak and limp mode on hard runs
- A direct upgrade path for cars that already have the factory oil cooler
What makes the Dinan High Capacity Oil Cooler different
Dinan’s high capacity heat exchanger delivers far greater cooling efficiency than the stock unit on factory oil cooler cars. By increasing cooling surface area and flow efficiency, it manages oil temperatures more effectively under sustained load, keeping the N54 in its sweet spot for longer. The result is consistent performance, enhanced engine protection and real peace of mind for fast road and track use.
