Great Product, less restriction at the AirBox.

Installed in 135i with no mods. Haven't noticed increased acceleration, but i think I'm getting slightly better mileage.

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.
