Manley Performance Race Flo Intake Valves are precision-engineered components designed specifically for the Chrysler 6.1L HEMI engine, covering model years 2005 through 2010. Built to meet the rigorous demands of bracket racing, drag racing, and oval track competition, these valves deliver reliable performance at engine speeds up to 8000 RPM. They are ideal for racers and performance enthusiasts seeking to optimize airflow and combustion efficiency, resulting in improved throttle response and enhanced engine durability under high-stress conditions.
Whether you are assembling a dedicated race motor or upgrading your performance engine, Manley Race Flo Intake Valves provide a dependable solution for maximizing intake flow and maintaining valve train reliability during intense track sessions.
Manley Race Flo Intake Valves incorporate advanced design and premium materials to ensure superior performance and longevity in demanding racing environments. Key features include:
These intake valves are crafted from high-quality materials selected for their strength and heat resistance, essential for the extreme conditions encountered in racing. The valves feature a balanced design that promotes smooth airflow and reduces valve float at elevated engine speeds. Manley’s Race Flo valves are engineered with precise stem and head geometry to ensure optimal sealing and durability under repeated thermal and mechanical stress.
A durable coating protects the valves from wear and corrosion, extending service life and maintaining consistent performance throughout race events or extended track use.
Manley Race Flo Intake Valves are direct replacements for the factory intake valves on Chrysler 6.1L HEMI engines from 2005 to 2010. Installation requires standard valve train disassembly and reassembly procedures and fits OEM cylinder heads without the need for modifications to valve guides or seats when installed by a qualified engine builder or machinist. These valves are compatible with stock valve springs and retainers designed for the 6.1L HEMI engine, requiring no cutting, drilling, or special tuning.
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!
