Valve Features and Additional info
JMTC Upgraded Stainless Intake valves are 1mm larger than the OEM valve and are a one piece forged valve for higher strength and reliability. JMTC uses high temp super alloy 21-4N and receive a high temperature friction reducing coating and work best with our long life steal guides. They have hardened tips so they can withstand both high-heat of a turbocharged engine and high-valve train stress loads of RPMs above the rev limit.
Our Valves are a great replacement for the OEM valve and do not require any changes to fit or work with all the OEM components regardless if you want to upgrade or not. While our upgraded Intake vavles can be used with the OEM or any manufacture exhaust valves they can not be mixed with other intake valves. So purchase them in a quantity of 8 for the 4cly Mini Cooper engine.
