Sodium Filled Inconel Exhaust Valvesview productsStainless Steel Black Nitride Intake Valvesview productsRacing Intake Valves Supertech Racing Intake Valves are engineered for precise airflow and high RPM stability. With lightweight options, optimized head profiles, and robust surface treatments, they deliver reliable sealing and repeatable performance for street, track, and competition builds. Key Benefits Why Choose Supertech Intake Valves High quality stainless and titanium options matched to your use case. Superfished stems for efficient flow. Unmatched dimentional tolerance. OE diameter and oversize options Highest seat eccentricity for better durability and longevity Materials & Surface Finishes Stainless Steel (21-4N/EV8) Strong hot hardness and corrosion resistance with precise stems and seat faces. Black Nitride treatment for reduced friction. Undercut and back cut for improved flow rates Titanium (Select Applications) Ultra-light for faster valve acceleration and increased RPM margin when paired with the right springs. CrN nitride for less friction. Used with any seat - guide. Surface Details Superfinish stems Backcut, Undercut for improved flow rates Unmatched dimentional tolerances. Engineering Options Geometry Flat, dished. Undercu, backcut Sizes OE diameter or oversized. Compatibility Match with Supertech springs and retainers for your cam profile, used with lash caps Works with performance guides and seat materials. Use Cases Street / NA Stainless intake valves provide durability and excellent sealing. Consider Black Nitride for added wear resistance and smoother operation. High RPM / Race Titanium intake valves reduce mass for quicker response and higher RPM. Use with the correct spring pressures and compatible retainers. Installation Notes Measure guide ID and set stem-to-guide clearance by material. Cut seats to proper angles and contact width; verify concentricity. Check installed height, seat pressure, coil bind, and retainer-to-seal clearance. Verify piston-to-valve clearance at intended lift and timing. Set valve lash or lifter preload per platform and cam specs. FAQ Do I need titanium intake valves? Titanium is ideal for high RPM and racing where reduced mass improves control. For most street and mild track builds, stainless intake valves are a robust, cost-effective choice. Is Black Nitride worth it on intake valves? BN can reduce friction and improve wear on stainless intake valves. Can I run oversize intake valves? Oversize valves can provide gains with ported heads and the right seat throat. Verify clearances and flow data before choosing. Do I need upgraded springs? Use springs matched to your cam profile and valve mass. Titanium valves typically require a properly selected spring and retainer set. Shop Exhaust Valves Shop Valve Spring Kits Shop Valve Guides
