Description Supertech Honda Acura RSX K20 30mm STD Flat Exhaust ValveWe manufacture our racing valves using only the highest quality materials available. We have spent countless hours studying these different materials as well as you applications to create just the right valve. Because of thermal fatigue the proper choice of material will greatly determine the valve performance and reliability. Supertech relentlessly test new materials to provide valves with unsurpassed fatigue resistance. These valves are black nitride coated, which is a hardening treatment that has been steadily growing in popularity over the last several years. These black Nitride coated valves feature harder surfaces and smoother finishes, providing less friction and subsequently longer life.  Specifications More Information Shipping Weight (Dimensional) 0.1000 Part Type Valves Make Honda / Acura Vehicle Group Civic Si 06-11 FA5 (Sedan), Civic Si 06-11 FG2 (Coupe), RSX Type S 02-06 DC5, TSX 04-08 CL9 Engine K20A2, K20Z1, K20Z3, K24A2 Manufacturer Supertech Stem Diameter 5.45mm Valve Length 108.65mm Valve Head Size Standard Valve Head Diameter 30mm Valve Type Exhaust Valve Stem Diameter 5.45mm Valve Material Stainless Steel Valve Finish Black Nitrided Valve Face Flat
