Set of 8 high performance oversize intake valves (+ 1mm) for the:
Suzuki GSX-R 1000 K1, K2, K3 and K4 (2000 - 2004) 
Suzuki GSX-R 750 K1, K2 and K3 (2000-2003)
 
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  airflow, 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 30,0 mm (+1mm) and can be installed in the stock valve seat.
 
We also have stock intake valves and exhaust valves (both stock and oversize) for these models. See our other listings.
