Enginetech part number IM4404 is a direct-replacement intake valve for 2000-2010 Acura/Honda/Saturn 3.2L, 3.5L, 3.0L applications. Key specifications: 1.378" head, 0.2160" stem, 4.570" overall length, nitrided stem.
Important Notes
- Nitride-hardened stem surface resists wear and galling in high-temperature and high-load applications.
- 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.
