I have put K & N filters on all my vehicles and it really makes a difference in performance especially at higher altitudes such as Wyoming where I live.

I used to have a K&N installed but the service people at the dealer tricked her into replacing it with a stock filter. I'll see how the green filter traps dirt in comparison to the K&N.

The air filter has a solid build and inserting it added a growl to the sound of my engine. The problem with this filter was that due to it's better quality material used it is slightly thicker and not as bendable as the factory filter, this gives it a very tight fit in the air filter compartment and one has to struggle quite a bit to close the air filter compartment tightly
