Good but Not Great

I've always liked K&N, but lately their products have been less than desirable. I ordered this product with missing parts. It says in the install instructions that there are supposed to be 2 washers to secure it to the factory airbox. These were not included upon it's arrival to my doorstep. So I had to instead go to a hardware store and get the appropriate 8x32 washers/screws to complete the install. You get 3 stars due to brand loyalty, otherwise you'd only get 1.

Adrenalin Owner Terrain Denali

I bought the K&N Air filter when I got my Terrain Denali as I do every vehicle I have owned. Easy maintenance for long term use and not a single problem with Turbocharged engines that even includes the F150 Ecoboost I once had.

K&N Filter

I bought a K&N filter and I noticed immediate improvement in acceleration. My car even runs smoother. Don't know mileage yet. I've had these filters in my other cars and I've never been disappointed. Over time they pay for themselves.
