Enginetech part number V2388S is a direct-replacement intake valve for 1996-2004 Ford 4.6L, 5.4L, 6.8L applications. Key specifications: 1.752" head, 0.2750" stem, 4.622" overall length, chrome stem.
Important Notes
- This valve is engineered for CNG and LPG bi-fuel engine service. Do not substitute a gasoline-only valve in alt-fuel applications.
- Stellite-faced valve. The cobalt-chromium alloy face resists the higher operating temperatures and dry-fuel wear seen in CNG, LPG, and propane service - a defining feature of the part, not interchangeable with a standard gasoline-spec valve.
- Select applications are specific to engine VIN codes: 9. Verify the eighth character of your VIN against the fitment data before ordering.
- Chrome-plated stem provides a hard, low-friction wear surface for extended service life.
- Always verify head diameter, stem diameter, and overall valve length against the OE valve being replaced before installation. Valve dimensions vary across engine families - a visual match is not enough.

Enginetech standard valves are stock-replacement engine valves produced from OE grade materials or better, engineered with the production engine rebuilder in mind. Face runout, stem finish, and stem diameter tolerances are held to some of the tightest standards in the internal engine parts industry, and every valve is inspected by on-site engineers against a documented quality plan before it leaves the plant. The line covers domestic, import, and common high-performance applications across a full range of head diameters, stem diameters, and overall lengths, with chrome-plated and nitride-hardened stem finishes available where the engine's operating conditions call for the upgrade. Always verify head diameter, stem diameter, valve length, groove count, and any oversize stem requirement against the original valve being replaced before installing, as multiple valve configurations can share the same vehicle nameplate.
