The Manley Performance Race Master Intake Valves are precision-engineered components designed specifically for Chrysler and Dodge 5.7L and 6.1L HEMI V8 engines from 2003 to 2008. Built to withstand the rigorous demands of bracket racing, drag racing, and oval track competition, these intake valves deliver exceptional durability and reliable performance at engine speeds up to 8000 RPM.
Ideal for serious racers and performance enthusiasts alike, these valves enhance valvetrain strength and longevity while maintaining optimal airflow for improved power delivery. Whether upgrading a stock engine or building a high-performance race motor, Manley Race Master Intake Valves provide the dependable operation needed under extreme conditions.
Manley’s Race Master Intake Valves incorporate advanced engineering and premium materials to ensure superior performance and durability for high-RPM HEMI applications. Key features include:
Manley Race Master Intake Valves are crafted from premium alloy steel and undergo a rigorous heat treatment process to achieve an ideal balance of hardness and toughness. This ensures excellent resistance to wear, deformation, and fatigue, even under the extreme heat and stress of high-RPM racing engines.
The valve faces and stems are precision-ground to exact tolerances, promoting consistent valve seating and smooth operation. The design optimizes airflow through the intake ports, enhancing volumetric efficiency and throttle response without compromising durability.
These intake valves are designed as direct replacements for factory valves in 2003–2008 Chrysler 300, Chrysler 300C, and Dodge Challenger models equipped with 5.7L or 6.1L HEMI engines. They fit OEM valve guides and seats precisely, requiring no special machining or modifications for installation.
Installation is straightforward for experienced engine builders and professional shops, and the valves are fully compatible with stock and aftermarket valvetrain upgrades designed for HEMI engines.
Manley Performance manufactures high-strength engine internals for serious builds—especially forged pistons, connecting rods, valves, and valvetrain components developed for racing and high-output street applications. If you’re building for boost, high compression, or sustained RPM, Manley is a common choice for parts engineered to take abuse and keep power reliable.
ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
