On Stock EXC-Fs this airbox will rob you of HP on the top end. Fuel adjustments with a tuner are absolutely necessary to get anything out of the vented cover for anything with EXC-F bike.

Pros: Excellent design.|Works great.
Cons: Need a black one.
Helps my bike breathe better and the low end power picked up a bunch.

Definitely helps the bike breathe better. Gives the bike a nice throaty sound when you open the throttle. Recommend checking and cleaning your air filter often after installing.
