CTS Turbo B-Cool Billet BMW 2.0L 3.0L Oil Filter Housing

Billet aluminium oil filter cap upgrade for BMW 2.0 litre and 3.0 litre engines. Replace the fragile plastic cover with a precision CNC machined, hard anodised alternative that improves durability and looks. This finned cap acts as a heat sink to aid oil temperature control and reliability under spirited driving, track days and tuned builds.

We run this part on our own cars and customer builds and it has been a brilliant reliability upgrade. Excellent fit, no fuss, and it keeps the lubrication system happy. A proper piece of kit for anyone who is tired of cracked OE caps and messy leaks.
