Part #: 12332H-8

Overview

The Manley Race Master 2.180" Triple Groove Race Flo Hollow Stem Intake Valve Set is engineered specifically for Chrysler’s 6.4L (392) HEMI engines from 2012 to 2014. Designed to meet the rigorous demands of bracket racing, drag racing, and oval track competition, these intake valves deliver the durability and performance required for high-RPM race applications. Whether building a dedicated race engine or upgrading your performance setup, these valves provide reliable operation up to 8,000 RPM, ensuring consistent power and efficiency under extreme conditions.

Manley Performance’s Race Master valves are precision-crafted to optimize airflow and combustion, helping serious racers and enthusiasts maximize their engine’s potential without compromising reliability.

Key Features

Manley Race Master Intake Valves combine advanced engineering and premium materials to enhance engine performance and durability. Key features include:

• Specifically designed for 2012–2014 Chrysler 6.4L (392) HEMI engines with a 2.180-inch valve head diameter
• Hollow stem construction reduces valve weight, improving valve train dynamics and enabling higher RPM capability
• Race Flo design optimizes valve head shape and surface finish to enhance airflow and cylinder filling
• Manufactured from high-strength materials to withstand the extreme heat and stress of competitive racing environments
• Engineered for reliable operation at engine speeds up to 8,000 RPM
• Precision ground and finished for excellent sealing and smooth valve train operation
• Set of 8 valves included, covering all intake ports for a complete upgrade

Construction & Design

These intake valves feature hollow stems that significantly reduce reciprocating mass, allowing the valve train to respond more quickly and reliably at elevated engine speeds. The Race Flo design improves airflow by optimizing the valve head’s geometry and surface finish, which contributes to better cylinder filling and combustion efficiency.

Manley’s meticulous manufacturing process ensures each valve meets strict tolerances for fit and finish, promoting consistent performance and long service life even under the harsh conditions of racing. The high-strength materials used provide excellent resistance to heat, wear, and fatigue, critical for maintaining valve integrity in high-performance combustion chambers.

Installation & Fitment

These Race Master Intake Valves are direct replacements for factory intake valves on 2012–2014 Chrysler 6.4L (392) HEMI engines. They fit precisely into existing valve guides and seats without requiring any special machining or modifications beyond standard engine assembly procedures. Installation is straightforward for experienced engine builders and machinists, but professional installation is recommended to ensure proper valve seating and optimal engine performance.

The valves are compatible with factory valve train components designed for 2.180-inch head diameter valves, making them an ideal upgrade for performance builds within the specified model years and engine configuration.
