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.
