Ever since I found out about K&N Air Filters, I have tried all the products and they all appeared to be extremely high in quality and performance. I'm sold on them and won't use anything else.

Great filter, low price and fast shipping. What else is there to say?

I have a 2005 4.2L V6 F-150 with 146k miles. I'm getting an extra 1 1/2 miles to the gal. since I installed the new fuel filter. And the delivery came in two days. That's the fastest I've ever got on line. Thanks.
