K&N Performance Filters have been well known in the automotive world for years, unsurpassed in airflow and filtering capability they are now one of the most used filters on the road today.   Now this technology is available and  FAA-PMA approved by Challenger Aviation for most general aviation aircraft. Made of a woven cotton fabric instead of paper,  the K&N filter medium for aircraft offers superior filtering without the restriction of airflow presented with paper or foam filters. Fabric allows 50% more air to pass than paper, and almost 60% more than foam! This translates into more horsepower and  improved fuel economy.

  Challenger High Performance filters with K&N filter media provide 2-4% more H.P. than conventional filters offering unmatched performance.  By eliminating the restrictions of your old filter, fuel economy will improve .3 to .5 gph.  

This means the filter will pay for itself in less than 150 hours!  

Throwing away your air filter every year and dealing with a sticky, oily mess is a thing of the past.  These filters can be easily cleaned and reinstalled  so it may well be the last filter you ever need to buy. 

Don't be fooled by other vendors that sometimes appear to be offering kits at a lower price.  Our kits come with everything necessary so you will have everything you need  when you go to install your new filter.  We even include enough cleaning solution to last for years!
