Stainless Steel Black Nitride Intake Valves
Supertech's Black Nitride intake valves are manufactured from premium stainless steel and finished with a proprietary Black Nitride surface treatment. This coating provides superior hardness, reduced friction, and enhanced wear resistance compared to standard stainless valves.
Each valve is precision-machined to OEM tolerances and undergoes rigorous quality control including dimensional inspection, hardness testing, and surface finish verification. The result is a valve that delivers consistent, reliable airflow and sealing in both street and competition applications.
Key Features
- Premium stainless steel base material for strength and durability
- Black Nitride surface treatment for reduced friction and wear resistance
- Precision-ground stem and face for optimal sealing
- Swirl-polished underhead for improved intake flow
- Compatible with standard valve guides and seats
- Available in standard and oversize diameters
Applications
Ideal for naturally aspirated, turbocharged, and supercharged engines where intake flow and valvetrain stability are critical. Lightweight titanium intake valves are also available for select applications where maximum RPM and reduced valvetrain mass are the priority.
