A pickup truck friend suggested I install a K&N filter on my Chevy 5.3L engine. I was careful to notice any difference in engine performance, and it is distinctly better, smoother and more powerful. Definitely worth the cost and modest amount of time to install. I've thanked my friend and now thank K&N here for a great product.

I am averaging more then 5 miles per gallon more on my 2014 chevrolet silverado 5.3 liter. My wife thought I was crazy, until she drove it and saw the savings herself. I will never use another filter again. K & N air filter is the best.

I bought the K&N Air Intake for my 2015 Chevy Silverado and I like the fact that it fit right in my air box and I love the fact that it is Life time.

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.
