Review part 33-2458
Thursday, August 13, 2015 - Part 33-2458
Have a 2011 335i sedan and it fit perfectly. Nice touch to have it pre-oiled out of the box. No doubts it will perform better than stock without the expense of upgrading the air filter system.

Slipped right in, 3 minute install max. Noticeable increased throttle responsiveness. Noticeable mpg boost. Additional off the line acceleration.

As soon as I changed out the air filters, I noticed the difference. Faster response time and quick to speed up. For the last 5 years, all of my cars have had a K&N air filter in them. Would recommend to anyone.
