When we tell you that Challenger Aviation Products manufactures the best aircraft air filters, that's not just a lot of hot air. They've been a family operated business since 1999, specializing in premium FAA/PMA certified air filters that use K & N filter media. Ever since retiring from a successful aircraft repair business, owner Chuck Rocco started this company to focus on developing quality filtration products for general aviation aircraft. We carry a selection of their replacement air filters, gaskets, installation kits and sealing grease. You'll also find a recharger kit, cover and quality windsocks. SkyGeek.com is your one stop shop for aircraft parts, supplies and equipment. In the hangar, on takeoff and in the air, we're there for you.
