Supertech Stainless Intake Valves for Nissan RB25DET NEO (+1.00mm oversize)

Supertech intake valves for the Nissan RB25DET NEO with the factory solid lifters, engineered for racing and high-performance builds. Crafted from premium materials with computer-optimized profiles for improved airflow, heat dissipation, and valvetrain stability at high RPM. Black Nitride surface treatment reduces friction and improves heat dissipation compared to uncoated valves. Proper installation requires cylinder head CNC machining, verifying valve-to-piston clearance and installed spring height during assembly. For a complete valvetrain refresh, pair with matched Supertech exhaust valves, valve springs, retainers, valve guides, and stem seals.
