Part number: AIVN-1103S-12 / SINGLE GROOVE
 
Supertech Engine Valves are engineered for high-performance street and racing applications, delivering exceptional strength, heat resistance, and precise fit.
 
This valve features a Single Groove lock groove, a Dished face profile, and measures Standard in diameter, with an overall length of 105.10mm. Built to precise standards, it ensures optimized airflow and long-term reliability.
 
Production begins with a one-piece forging, where the head is formed under a slow two-step process to maintain optimal material grain flow. Each valve undergoes multiple CNC machining steps, stress-relieving heat treatments, and either nitride hardening or application-specific coatings.
