GSC 2222-8 Intake Valve Set, 38.4mm, for Ford F-150 5.0L Coyote Gen 4

Vehicle Fitment

• 2021-2026 Ford F-150 (5.0L Coyote Gen 4)

Fitment Notes

• Intake valves - sold as a complete set of 8
• 38.4mm head diameter, standard size
• Matching exhaust valve set for this engine available separately (GSC 2221-8)
• Confirm your Coyote engine is specifically the Gen 4 revision before ordering, as valve dimensions differ between Coyote generations

Features

• Engineered using advanced 3D design and flow simulation software for a stronger, higher-flowing valve head design
• Flow-tested in application-specific configurations to ensure maximum airflow versus stock valves
• Reduced valve face distortion compared to competing designs, improving long-term sealing under extreme conditions
• Back-cut valve design reduces weight for higher RPM capability, higher boost tolerance, and compatibility with more aggressive cam profiles without increasing spring seat pressure
• Micro-polished valve stems reduce oil retention and drag against the guide for smoother valvetrain motion
• Manufactured from premium stainless steel for high-heat, high-output engine durability

Specifications

• Type: Intake Valve Set
• Head Diameter: 38.4mm (Standard)

Product Description

The GSC 2222-8 intake valve set brings GSC's advanced valve head design to the 5.0L Coyote Gen 4, engineered through 3D modeling and application-specific flow testing to outperform the stock valve's airflow characteristics. Reduced face distortion versus competing designs helps the valve maintain a consistent seal under the extreme heat and pressure of high-output street or track use.

The back-cut head design trims valve weight to support higher RPM operation, increased boost pressure, and more aggressive camshaft profiles without demanding higher spring seat pressures to control valvetrain motion. Combined with micro-polished stems for reduced stem-to-guide friction, this set of 8 intake valves pairs naturally with GSC's matching 2221-8 exhaust valve set for Coyote Gen 4 owners building a complete, high-flow valvetrain package.
