Manley 12202HBC-8 Titanium Intake Valve Set NRE X1/PM 2.400" 6.400" .3415"

The Manley 12202HBC-8 is a high-performance titanium intake valve designed for Noonan Race Engineering (NRE) X1/PM racing applications. These valves provide exceptional strength, lightweight construction, and durability for engines that demand the best, with premium titanium alloys ideal for high-revving engines where reduced weight is crucial for improving valvetrain performance and RPM potential.

Key Specifications:

• Head Diameter: 2.400 inches
• Overall Length: 6.400 inches
• Stem Diameter: 0.3415 inches
• Intake application

Premium Construction Features:

• One-piece forged construction with grain flow, not a head welded to a stem
• Machined in state-of-the-art CNC turning centers and valve stem grinders to exacting tolerances
• Premium titanium alloys that balance mechanical properties, hardness, ductility, and fatigue strength at specific temperatures
• Micro-polished surface finish that eliminates potential stress risers and increases fatigue strength
• "H" suffix indicates higher hardness material
• "B" suffix indicates Bead Loc® keeper groove
• "C" suffix indicates premium CrN seat coating

The lightweight design reduces overall valvetrain mass, allowing for quicker valve action and increased throttle response, making them perfect for drag racing, road racing, and high-performance street applications. Each valve undergoes stringent final inspection to ensure uncompromising quality, performance, and reliability, with strict quality control measures enabling delivery within tight tolerances.

Important Installation Note: These valves do not come with a hardened tip, and tip protection is required. Manley recommends using wear cap P/N 42104, 42104TM, or Manley LocCap System for proper tip protection.
