10-SC450 KPMI, cast iron valve seat. 45mm OD

Kibblewhite Precision Machining produces these high-grade cast iron valve seats in the U.S.A. to meet the demands of modern combustion environments. They are fully compatible with leaded and unleaded fuels, as well as methanol and ethanol blends. This particular seat has a 45.00mm outside diameter, a 34.50mm inside diameter, and an 11.00mm height. Because they offer excellent thermal transfer and resist micro-welding, they are equally at home on the intake or exhaust side of the cylinder head. The inclusion of a leading edge ensures a smoother installation process into the head casting. These universal seats are sold individually and provide the durability required for both street and performance applications.
