This is a set of 16 Supertech Stainless Steel Black Nitrided Valves for Nissan SR20 SR20DET 2.0L Engines. Supertech only offers the higher quality Inconel Valves for the exhaust side of this engine. So this is a combination of Stainless Steel Intake Valves, and Inconel Exhaust Valves.
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.
