This is a set of 16 Supertech Stainless Steel Black Nitrided Valves for Honda Acura K20 K20A3 Engines.
Supertech has been around for a long time in the Valvetrain industry, and has race proven their product year after year, and backed it up with world records and first place trophies. We use Supertech in our top level engine builds for good reason. We suggest Supertech Valvesprings and Retainers and actually use them in some of our very own cars.
Dished Face Valves are designed for Low Compression Forced Induction (Turbo/Supercharged) engine setups.
