Challenger Aviation Piper Navajo Air Filters

FAA/PMA/STC Certified

Challenger high performance air filters are made with K&N filter media and are FAA/PMA approved for most Piper Aircraft.  They are cleanable up to 25 times, Coast Guard approved and no AD’s.  Challenger cotton air filter media catches the smallest dirt particles that can wear out your engine.  The low restrictive design allows more air to flow into your engine for a power increase and fuel savings up to one gallon per hour. 


Challenger high performance filters are American manufactured. These air filters have been in service 10 years. Our products are environment friendly.  Challenger filters are certified under a STC so a onetime 337 is required and you are ready to enjoy the benefits.


“This could be the last filter you ever buy.”
