news flash for air filter consumers... K&N makes cabin air filters. No more wasting money every 15 thou miles on a dealership rip off pricing

So, for the hard facts, it costs 2wice what a Fram or STP does (17 bucks vs 39) http://www.autozone.com/1/categories/kia-sportage-ex-cabin-air-filters

You only ever have to buy one. Yeah, you'll have to keep buying the other brands, but only buy one K and N.

My K and N 6 pack intake filter (1969 Super Bee and R/T) has been with me for 20 years. Never had to buy another, and only once had to buy a new can of oil. Beat that!

ALSO!
I just learned that K and N has a need for some vehicles to use for research and development...

Or maybe you live closer to the other 2 locations where they need vehicles

Warrington, Cheshire, England - K and N Filters Europe LTD

Eindhoven, the Netherlands - SRM (Europe) BV

I just learned that K and N also has an annual car show, http://www.knfilters.com/news/news.aspx?id=5597  and a newsletter http://www.knfilters.com/register/newsletter.aspx 

The annual show is in response to the Fontana (AAA race track) location of the Detroit Speed Road Rally 

The majority of the Optima Search for the Ultimate Street Car competitors arrive a day or two before the USCA event in Fontana and they all love their cars. So why not host a car show at K and N Filters’ corporate headquarters and manufacturing facility in Riverside, California to welcome the competitors and share the experience with K and N employees?
