MMR PERFORMANCE N55 SUMP BAFFLE

MMR20-0501

It’s well documented that the N55 engine found in the M135i and M235i  is prone to oil starvation issues when pushed hard on the road and even more so when used on track.

The MMR Performance sump baffle 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 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 it's effectiveness, plus highlighted that it's typically most susceptible without a baffle 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.


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

 

Please note, this doesn't fit the M135i X-Drive

MMR SUMP BAFFLE FOR MY M135I

Fitted it today total job time 5 hours ish , very impressed with the baffle obviously a lot of research gone into the design. after removing my sump I can see why if you track the car you would have oil starvation with a completely open sump !!! I do drive spiritedly and I have uped the power on my car it's 500+bhp so this is definitely worth thinking about as a precaution for you pride and joy first time buying of MMR great service and would highly recommend.

Heard about the sump baffle on Instagram and ordered it over the website. Customer service was fast and friendly. I am also really happy with the high-quality workmanship.
