Duque Hoodliner Productions was created to show and inform car owners about the aircraft firewall material hood liners. We fabricate and sell for Ford Mustangs, Thunderbirds, Buick Grand Nationals, Chevy Camaros, Corvettes, Jaguars, and many other cars. They're a better alternative to Dynamat, W-M-S, and other aftermarket insulators, but don't just take our word for it! Our hoodliners have an acoustic and thermal insulation that is FAR more superior to the stock foam pressed fiberglass liners that come from the factory. Our insulators are made of ¼ inch thick flexible rubber foam that is effective to over 225 degrees F. The material stands up to forces and temperature fluctuations that cars experience by keeping the exterior of the hood cool while not reflecting engine heat back down toward your intake. The material is also used by NASA!
