Supertech Black Nitrided +1mm Oversize Intake Valves for Nissan RB25 - Set of 12 - NIVN-1052-SL-12
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Engineered for high-performance Nissan RB25 engines, this set of 12 Supertech intake valves features a +1mm oversize head diameter to significantly increase airflow and volumetric efficiency. These valves are a critical upgrade for builds where the factory valve size restricts top-end power delivery.
Each valve is manufactured from high-tensile stainless steel and undergoes a specialized Black Nitriding process. This surface treatment creates a micro-smooth, hardened finish that reduces friction against the valve guide and provides superior resistance to wear and heat-induced corrosion. These attributes are essential for maintaining valvetrain stability in high-RPM or forced-induction applications.
- Fits: Nissan RB25 engines
- Component: Intake Valve
- Sizing: +1.00mm Oversize
- Finish: Black Nitrided coating for reduced friction
- Material: High-strength stainless steel
- Quantity: Set of 12 valves
- Manufacturer Part Number: NIVN-1052-SL-12
Note: Installation of +1mm oversize valves requires professional cylinder head machining to enlarge the valve seats for proper fitment and sealing.
