Xceldyne X2 Valve Seats - Intake - (+.010) X2ISM1494-290

Exhaust Valves

X2 seat materials are designed to improved 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 5-7 times faster and is superior to stock seats
Extends valve life where valve contacts seat, known as seat erosion
Require minimal machining and are available in both standard and +.010in. oversizes for standard valves
