I love mine on my F-350 diesel 4x4 gave me a little more pep and roughly 2mpg. Easy to clean. I have many K&N products, only way to go

I was amazed at how quick and easy it was to find what I was after on-line and then complete the purchase in a matter of minutes. The free shipping was great too (I live in Alaska). My F350 already runs better with the new K&N filter in place! THANKS!

After replacing the factory air filter with the K&N filter on my F-250 diesel, I noticed an increase in horse power. I am very satisfied with the purchase and would recommend it to anyone looking to increase the horse power of their truck.
