Supertech Mazda/Duratech 2.3 Stainless Steel Black Nitride Intake Valves - MAIVN-2301D-8
Supertech intake valves for the Ford Duratec 2.3 are engineered for racing and high-performance builds. Key specs: Material: stainless steel 21-4n, Head diameter: 35.00mm (std) dish, Stem diameter: 5.48mm, Overall length: 103.40mm, and Groove: single groove. Crafted from premium materials with computer-optimized profiles for improved airflow, heat dissipation and valvetrain stability at high RPM. Ideal for naturally aspirated, turbo and nitrous engine builds. For a complete valvetrain refresh, pair with matched Supertech exhaust valves, valve springs, retainers, valve guides and stem seals. Black nitride surface treatment reduces friction and improves heat dissipation versus uncoated valves, and proper installation requires verifying valve-to-piston clearance and installed spring height during assembly. Backed by Supertech's reputation for valvetrain precision and racing reliability.
