All years
 
Perfect replacement for your worn out stock valves - ready to install.
 
Made of the best grade stainless steel (EV8 / 21-4N) commonly found in high performance valves used for racing or modified engines (N/A, turbo or nitrous), these are a great improvement over the standard valves in strength and heat resistance.
 
These valves are finished with a durable black nitride coating to avoid stem wear and increase durability. These valves also have hardened valve tips.
 
Race Series is our new design with a 30º Back Cut to improve airflow and smooth the transition to the seat area as well as other improvements aimed at saving weight by optimizing valve dimensions.
 
These valves are 32,5mm (1,0mm oversize) and are designed to work with the original valve seat requiring only usual valve seat machining.
 
Oversize valves are a great way of increasing port flow for modified and big bore engines.
 
We have stock and oversize intake valves (+1mm), stock exhaust valves, as well as upgraded valve springs and titanium retainers for the CP2 engine.
