Part #: 11696HB-8

Overview

Manley Performance Race Flo Intake Valves are precision-engineered for high-performance Chrysler 5.7L VVT HEMI engines from 2009 through 2024. Designed to meet the rigorous demands of bracket racing, drag racing, and oval track competition, these valves deliver exceptional durability and reliability at elevated RPMs. Ideal for engines operating up to 8000 RPM, they optimize airflow and combustion efficiency to enhance throttle response and overall engine performance.

Whether you are building a dedicated race engine or upgrading your performance build, Manley’s Race Flo intake valves provide the strength, precision, and consistency needed for sustained power delivery under extreme conditions.

Key Features

Manley Race Flo Intake Valves incorporate advanced design and manufacturing techniques to maximize performance and durability in high-RPM applications. Key features include:

• Hollow stem construction reduces reciprocating mass, improving valve train dynamics and enabling higher RPM operation.
• 2.080-inch valve head diameter optimized for increased airflow and combustion efficiency in 5.7L HEMI engines.
• Bead Loc groove design enhances valve spring retention and stability under high-load conditions.
• Race Series quality ensures durability and reliability for bracket, drag, and oval track racing environments.
• Manufactured to precise tolerances for consistent fitment and performance in factory cylinder heads.
• Engineered specifically for intake valve applications to maximize volumetric efficiency and throttle response.
• Compatible with stock and aftermarket valve springs designed for high-RPM use.

Construction & Design

These intake valves feature hollow stems that significantly reduce overall valve weight, decreasing valve train inertia and allowing quicker valve action at elevated engine speeds. The critical bead loc groove securely retains valve springs, preventing spring movement and ensuring stable valve operation during aggressive driving and racing conditions.

Manufactured from high-strength materials and subjected to rigorous quality control, Manley Race Flo valves are built to withstand the stresses of high-RPM racing engines. Precision machining and finishing guarantee optimal sealing and durability, contributing to improved engine efficiency and longevity.

Installation & Fitment

Designed as direct replacements for intake valves in 2009 and newer Chrysler 5.7L VVT HEMI engines, these valves fit factory cylinder heads without modification. Installation follows standard engine assembly procedures and requires compatible valve springs suited for high-performance use. No cutting, drilling, or special tuning is necessary, making these valves a straightforward upgrade for race engine builders and performance enthusiasts.

What's Included
