Install couldn't be easier. Post install there is noticable extra power when accelerating to pass at freeway speed. No figment of the imagination as my wife and dad also noticed (and didn't know I put in a new filter). Getting an extra 3 miles per gallon highway haven't noticed an increase in city MPG.

Recieved product in under a week. For my Subaru it was as easy as unlocking the latches and replacing the filter. Seemed to already make a difference.

I put K&N filters in every vehicle I own and have never been disappointed. I immediately noticed an increase in power and just a smoother running engine. I also have been getting 34-35 mpg since I installed the air filter.
