Description

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!

The ultimate N55 bolt-in solution available to protect your engine’s longevity.

The problem is especially pronounced under hard braking, when the oil pools at the front of the oil pan under the lateral g-force, allowing the pick-up to run dry. Even a fraction of a second of no oil feed can be enough to do lasting damage to your engine, any longer and it’s almost certain to lead to engine failure. And that’s where our baffled sump comes in.The MMR Performance baffled sump has been extensively engineered from the ground-up to provide effective oil control, reducing surge and maintaining a more constant oil pressure; it’s the ultimate bolt-in solution available to protect your engine’s longevity.Featuring a total of 7 sophisticated one-way oil control flaps and specific baffling, the T-6061 anodised MMR sump baffle has been tested over thousands of miles of track and road use; the data we collected has proven its effectiveness, plus guaranteed that the baffled design prevents the oil surge problems once and for all.
