The Honda 14711-Z5T-900 Intake Valve is a genuine OEM component designed for a wide range of Honda GX340 and GX390 horizontal shaft engines, EB, EG, EM, and EU series generators, WT40 water pumps, and HS and HSS series two-stage snow blowers. As a direct Honda OEM part, it is manufactured to the same specifications. Confirm compatibility by matching part number 14711-Z5T-900 to your unit's serial number using the fitment table below, as Honda supersedes parts at serial breaks across this broad range of applications.
Key Features
- OEM Valve Geometry — manufactured by Honda to the exact head diameter, stem diameter, and face angle of the original, ensuring correct sealing against the valve seat and accurate flow through the intake port
- Direct OEM Replacement — this intake valve drops in as a like-for-like replacement with no machining or adaptation; designed to work with the existing valve spring, retainer, and guide
- Broad Fitment — fits GX340 and GX390 horizontal shaft engines, EB3800, EB4000, EB5000, EB6500, EG5000, EG6500, EM3800, EM4000, EM5000, EM6500 generators, EM7000 and EU6500 inverter generators, HS928, HS1332, HS1336, HSM1336, HSS928 and HSS1332 two-stage snow blowers, and the WT40 water pump — verify your serial number before ordering
- Combustion Integrity — a worn or burnt intake valve allows compression to leak past the seat, causing hard starting, rough running, and loss of power; a correctly sealing replacement restores full cylinder pressure and smooth operation
The intake valve controls the flow of the air-fuel mixture into the combustion chamber. On each intake stroke, the valve opens to admit the charge and then closes tightly to seal the chamber so compression can build. Over time, the valve face and seat can wear, burn, or develop carbon deposits that prevent a clean seal. When that happens, compression drops, the engine becomes difficult to start, runs unevenly, and loses the power output the equipment depends on. Replacing the intake valve with a genuine Honda part restores the tight seal the combustion cycle requires and brings performance back to spec.
