Expert's advice:
K&N's replacement air filters are designed to increase horsepower and acceleration while providing excellent filtration. The filters are washable and reusable and are custom designed to fit into your existing factory air box. Their drop-in design means adding performance is simple. With most vehicles, you simply remove the disposable air filter and replace it with a K&N. This will be the last air filter your vehicle will ever need.

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.
