*Complete Set of 12 Intake, 12 Exhaust Valves and 48 Keepers*
Our stainless steel intake valves are manufactured from an enhanced version of EV8 (21-4N) steel. We have chosen this material specifically because it’s the highest grade of steel available and provides the strength to withstand just about any application. Our exhaust valves are made from EV16 (21-8N) or EV8-Nb/w for even greater strength at higher temperatures. Our stainless steel valves are one piece forged valves, and depending on the application feature hardened tips, hardened seats, swirl polish, undercut, and our black nitride coating. Our black nitride coated valves feature a harder surface area and a smoother finish, providing less friction and subsequently longer life.
Supertech manufactures a variety of high performance Inconel valves for many applications. Supertech Sodium Filled Valves made of Inconel / Nimonic alloy offer a significant reduction in valve head temperatures that are required for today’s modern turbo engines. A cooler valve improves the material strength and durability while allowing the tuner more flexibility and a wider range of spark timing advances. Combine that with an average weight reduction of 10% and there isn’t a cooler valve on the market.
