MMX Performance - Baffled oil sump | BMW N55 F2x & F3x | M135i | M235i | 335i | 435i

It’s well documented that the N55 engine found in the M135i I M235i I 335i I 435i is prone to 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 really is an essential upgrade. Total engine failure is a very real possibility if not. Ask us how we know....!

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 this 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 where the data we collected has proven its effectiveness, plus highlighted that it's baffles correct the worst surge problems under hard braking.

Unlike other solutions available that require a plate to be welded in, the MMR solution is simply bolted into place making the addition of the baffle considerably easier and more accessible to install.

Fitment really is an absolutely essential insurance policy for any hard-driven N55 F-series car. 

Note: For reference, normal idling pressure when warm is 1.5 bar.

NOTE: Does not fit x-Drive Models.
