This is a second filter for the same vehicle. Since I live in the Pacific Northwest, having two filters allows me to have a clean filter ready to install and I don't have to worry about the humidity or rain (for cleaning and drying purposes). I remove one and clean it and install the dry freshly oiled one. This is also the second vehicle that I have had K&N filters in. I highly recommend these filters and systems.

As always, very satisfied with K&N product. Every car/truck has one installed. It is usually first item I get, after buying a new car/truck.

Filter fits well. Am looking forward to it doing a good job for me like all the K&N filters I have purchased in the past have done.

I could tell an immediate difference after replacing the stock air filter in my 2011 GMC Sierra with the K&N filter. Engine performance increased dramatically. I am very pleased.

Have been using K&N filters for over 25 years. Raced Dirt track for 10 years so I saw how good the K&N filters are, paper filters were junk, even the best (highest priced) would have tell-tale streaks of dust on the air cleaner plate. No dust with K&N. Engines cost too much to not properly protect and K&N did an outstanding job. Ran some engines two years without having to refresh and won a lot of races. One of the only driver/owners to actually make more money in winnings than it cost to race and I did it without ANY sponsors. I have 4 trucks, 4 motorcycles, and a lawn mower that all run K&N's. If it has an engine, it will have a K&N.
