The k&n air filter added 6 miles to the gallon on my 2008 land rover. I have used the air filters in my last 6 vehicles. I am very pleased with this product.

Great product! I ordered it to clean the air filters on my Triumph Bonnevile and it worked great.Super easy to follow instructions.

I have installed K&N air filters (and occasionally oil filters) in every vehicle I've owned in the last 15 years. The latest is my new 2014 Triumph Street Triple motorcycle. Love the change in induction noise, and I like the idea that my bike's breathing freer, even if the change isn't noticeable in increased power. The simple fact that these things last forever is enough to sell me. Keep up the good work, K&N!
