Multi-layer air filter gaskets with built-in screens are high-performance automotive components engineered to seal the intake hat or injector scoop to the top of a roots-style or screw supercharger. They simultaneously act as a debris barrier and pressure seal to prevent catastrophic engine failure if external particles bypass the primary air cleaner Multi-layer air filter gaskets for blowers are specialized seals that combine a structural mounting gasket with an integrated wire mesh or micron filter. They are designed to prevent boost or vacuum leaks while simultaneously stopping harmful airborne debris from being ingested into the blower rotors or engine.
