Supertech Intake Valves for 2007-2013 BMW M3 (E92) S65 32v 4.0L V8 Engines
BMIVN-1065
Head Diam: 35.40mm (STD)
Stem Diam: 4.97mm
Length: 111.75mm
Material: Black Nitride
Valve Type: Intake
*Single Valves Are Also Available In The Drop Down Menu Below*
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.
