Because Fel Pro OEM is a global producer of engine and sealing products, Fel Pro Performance Gasket can benefit from Fel Pro’s proven expertise in engineering and manufacturing OE components and subsystems for the world’s major automotive manufacturers. Fel Pro OEM extensive field experience gives Fel Pro Performance, insights into the expected changes in engine components over time. Fel Pro Performance designs there aftermarket sealing parts to meet your specific needs in the Performance environment.
Fel-Pro® Performance Head Gasket line is the engine repair solution for high-performance engines. Fel-Pro® brand performance head gasket are specifically designed to handle higher compression ratios, special cam timing and higher operating temperatures. In addition, Fel-Pro® brand performance head gasket are ideal for engines that are supercharged, turbocharged or use nitrous oxide.
The Fel-Pro performance head gasket line includes:
PermaTorque® wire-ring design
In the brutally tough environment that typifies a performance engine, Fel-Pro performance head gaskets deliver superior sealing performance.
Fel-Pro performance exhaust header gaskets, the performance version of an exhaust manifold gasket, resist blowout and burnout and provide good exhaust flow.
Fel-Pro performance exhaust header gaskets consist of a high-density fiber facing material attached to both sides of a perforated steel core. This design provides a durable gasket that will seal slightly warped surfaces.
Also, we use an anti-stick coating that allows the gasket to move without sustaining damage and helps the gasket accommodate the expansion and contraction of the head and headers.
Fel-Pro designs the exhaust header gaskets with “slotted” bolt holes so you can easily slip the gasket in place and then tighten the bolts. The high-density fiber retains the torque to ensure the gaskets seal
Fel-Pro performance intake manifold gaskets must prevent air, oil and dirt from being sucked into the intake ports and prevent coolant from leaking out of the coolant ports. For performance engines, this is complicated by the variety of aftermarket cylinder heads and intake manifolds in use.
Fel-Pro performance intake manifold gaskets have been tested for use with most all aftermarket cylinder head and intake manifold combinations. In addition, most Fel-Pro performance intake manifold gaskets do not have a metal core, which allows engine builders to trim the gasket to ensure an exact fit on modified ports.
Fel-Pro offers a solid-core intake manifold gasket for high-vacuum race engines, as well as performance applications that have a long expected service life — i.e., street machines, marine use or tow vehicles. The solid core provides extra strength and stability, and the gaskets come in proven port shapes used in race intake gaskets.
Fel-Pro Performance Valve Cover Gaskets Fel-Pro engineers have developed a complete line of performance valve cover gaskets using a variety of technologies and materials to ensure a proper seal in performance applications.
The available options make it easy to find the ideal gasket to meet specific requirements for application suitability, features and cost.
Fel-Pro performance rear main seals handle the unique needs of the professional racing engine builder. Fel-Pro offers special materials and design configurations optimized to perform under high crankcase vacuum conditions, elevated temperatures and high RPM levels. Racers depend on these seals for leak-free performance both on the track and on the street.
Seals are made of high-grade synthetic rubber materials, such as polyacrylate, silicone, Viton® and polytetrafluoroethylene (PTFE), so you can choose the best high-heat and abrasion-resistant sealing characteristics for your application.
