Expert's advice:
The N55 engine is no stranger to oil cooling problems, that’s why we developed the MSL Oil Thermostat. A highly recommended upgrade for the N55 engine, especially when it’s tuned. Instead of opening at 105°C, the MSL Oil Thermostat opens at 85°C which results in an operational oil temperature 20°C lower than OEM. The MSL Oil Thermostat allows the engine to reach operating temperature at the same time as a stock thermostat. It’s made from a solid block of high-grade aluminium at our own facility and takes only 30 minutes to install.
Note: Does not fit on the BMW 335i N55 Active Hybrid, please select the S55 thermostat for this car (the S55 fits on the 335i active hybrid).

MOSSELMAN tuning experiences
With Mosselmans' performance package I exceeded even more than the company advertised on their website! The information sharing process was easy and hassle-free. Excellent customer service from Leon and his team!
Mosselman tuned my BMW 318d today. What a result, it became a completely different car! Very professional company and friendly staff. This was my second car here and again they have exceeded my expectations. Thanks!
Very happy with my improved car, the car reacts better on the throttle and is very direct. Also, the exhaust sounds better!
Visited Mosselman on May 24th for the chip tuning of my 135i, great result! The adjustment is great, when will you post the photo on FB :)?
After 1,5 years still very happy with my iTronic. By far the best upgrade I could have done with my BMW 340i.
