K&N Replacement Air Filter
  • Designed to Increase Power
  • Million Mile Limited Warranty
R Wallace, Searcy, Arkansas
I have been an avid K&N customer for almost twenty years. Their air filters do extract more power and/or torque from your vehicle and offer longer life via their rechargeable design. All of my vehicles now use K&N air filters. Their website however can be confusing. With my last purchase, I entered the product and promptly received a message saying my shopping basket was empty. I re-entered the data and got the same response. Apparently, that occurred due to a backorder situation and the response was not intuitive. Subsequently, I contacted their customer service and like their products, got a friendly, high quality response. Great products, great people, but less than stellar web presence.

The only thing that would make it any better was if it was a little cheaper.

This filter replaces one with 80,000 miles on it. Very pleased with this product. Well worth the investment I will continue to use K&N filters in all my engines.
