ENGINE 208 X2 VALVE SEATS •X2 seat materials are designed to improve heat transfer from the valve, minimize valve bounce, provide excellent sealing capabilities and increase the service life of titanium or steel valves •Replace factory seats that are prone to causing wear issues and premature valve failures •Heat dissipation (thermal conductivity) is increased and is superior to stock seats •Extends valve life where valve contacts seat, known as “seat erosion” •Requires minimal machining and is available in both standard and +.010” oversizes for standard valves •Precision CNC machined for dimensional accuracy, flatness and roundness with a typical interfer- ence fit of .004”-.005” •Two per kit SUG.
