Introducing our new line of Delta Force air intake panel filters. This is a great and economical way to add some extra performance and filtering protection for your 1985-2006 GM car/truck/van/suv with a factory flat-panel style filter. These premium air filters are designed as a direct replacement and fit snugly in the factory airbox thanks to the durable black urethane outer frame/seal. The high-flow red woven cotton gauze filtration media comes pre-oiled and is ready to drop-in out of the box for a quick and easy installation. Another bonus is the filters are serviceable with our Delta Force Performance Filter Refresh kit part #615001 and with a proper maintenance schedule, should be the last air filter you buy for your vehicle.
