Mr. Gasket Performance Intake Gaskets are manufactured from cellulose/nitrile composition gasket material. This is a low density material that conforms well to irregular surfaces and has very good crush resistance at high flange pressures. They provide excellent sealing and durability as the material is designed for sealing gasoline, oils, water and coolant in applications up to 350 degrees Fahrenheit. While die-cut for an excellent fit, they can be trimmed if necessary for modified port applications. For original equipment replacement, high performance street, drag race and oval track.
