Tax excluded. Shipping calculated at checkout
It’s well documented that the N55 engine found in the M135i, M235i, 335i and 435i is prone to severe oil starvation issues when pushed hard on the road and even more so when used on track.
If you're ever planning to use your car on track, or even particularly hard road driving, this is an essential upgrade. Total engine failure is a very real possibility if not - ask us how we know!
