Fel-Pro Exhaust Header Gaskets come in varying levels of performance to fit any budget and driving style. All header gaskets are sold in pairs unless specified otherwise.
Fel-Pro Performance Gaskets: Consists of high-density fiber attached to both sides of a perforated steel core. The fiber has great torque retention qualities and these gaskets can even seal slightly warped surfaces and resist blowout/burnout from high-temp exhaust gas. A nonstick coating allows motion without damage, which simplifies gasket removal for servicing.
Fel-Pro Performance HTA Gaskets: Feature a triple-layer proprietary high-temp alloy (HTA) and coating to withstand up to 1600 degrees Fahrenheit. They have an embossed sealing bead that acts like a spring, maintaining a perfect seal under virtually any operating condition. A propriety coating ensures sealing over a broad range of surface finishes.
