Supertech black nitride coated stainless steel single groove inlet valves for the MINI Generation 2 R56 Cooper S and JCW N14 & N18 engine.

Supertech Black nitride coated valves are feature-packed to deliver performance to a forged engine build. Using the Supertech inlet valves will improve strength and durability of the N14 or N18 engine giving that extra peace of mind when pushing the engine hard over long periods of time. 


The stainless steel construction is precision machined and highly heat resistant to ensure the durability of the valve. The Black nitride coating on the inlet valve reduces friction so improves engine efficiency and output. 
The back cut profile of the inlet valve optimises gas flow to improve performance.

Supertech inlet valves are sold as a set of 8 valves as required in the N14 MINI Cooper S and JCW engine.

Q. Do I need beehive springs with these valves?
A. No, but beehive valve springs improve the return rate of valves allowing them to operate quicker than valves running with standard valve springs. Ideal for highly tuned MINIs. 

Q. Why are inlet valves not available in Inconel alloy to match the exhaust valves?
A. There's no need for the Inconel alloy to be used here because temperatures are not as high as the exhaust side. Supertech Intake Stainless Steel Nitride-coated Valves are sufficent.
