Manley 11485-8 Titanium Intake Valves 1.840 in. Head Diameter

Manley Performance 11485-8 titanium intake valves deliver race-proven performance for high-revving, high-demand engine builds. Designed for high-performance and racing applications, these valves provide exceptional strength, lightweight construction, and durability for engines that demand the best.

Key Features:

• One-piece forged construction with grain flow, ensuring durability and minimizing potential weak points compared to head-welded alternatives
• Meticulously machined in state-of-the-art CNC turning centers and valve stem grinders, maintaining exacting tolerances for optimal valve performance
• Finest titanium alloys used for both intake and exhaust applications, providing the best balance of mechanical properties, hardness, ductility, and fatigue strength at operating temperatures
• Micro-polished to a jewel-like surface finish — a process that eliminates potential stress risers and increases fatigue strength
• Ideal for high-revving engines where reduced valvetrain weight is crucial, allowing for quicker valve action, increased throttle response, and compatibility with aggressive camshaft profiles
• Each valve undergoes a stringent final inspection process to ensure uncompromising quality, performance, and reliability

Manley Performance is recognized as a leading manufacturer of performance and racing valves, making these titanium valves a trusted choice for drag racing, road racing, and serious high-performance street builds. Note: Titanium valves require a hardened tip insert or tip protection — hard tip is not included.
