Manley 11696B-8 Race Flo Intake Valve 2.080" Black Nitrided for HEMI 5.7L

Featuring Manley's signature Race Flo profile, these valves use a back-cut, radiused face geometry that improves airflow into the combustion chamber over stock valves, supporting increased horsepower in performance street and racing applications.

Each valve measures 2.080 inches in head diameter and is finished with Manley's Black Nitride (B/L) surface treatment. Black nitriding significantly increases surface hardness and wear resistance while providing corrosion protection — making these valves an ideal upgrade for high-performance HEMI builds running aggressive camshaft profiles or forced induction.

Key Features:

• Race Flo back-cut face design for improved airflow and flow efficiency
• 2.080" head diameter — direct replacement for HEMI 5.7L intake positions
• Black Nitride surface treatment for enhanced hardness, wear resistance, and corrosion protection
• One-piece swirl-polished stem for reduced friction and improved seal wear
• Designed for high-RPM and high-lift camshaft applications

Manley Performance has been a trusted name in professional racing valve technology for decades. The 11696B-8 valves are a proven choice for HEMI 5.7L performance builds seeking reliable, high-flow intake valve solutions.
