The Honda 89216-VJ3-J10 Plug Wrench (16X19) is a genuine OEM service tool designed for GX25, GX35, and GX50 horizontal shaft engines, HHT25 trimmers, and WX10 water pumps. As an OEM-sourced tool, this wrench is the exact instrument Honda specifies for spark plug service on these compact units — ensuring the correct size engagement every time. Verify your machine's model and serial number against the fitment table before ordering, as Honda supersedes service tools at production breaks.
Key Features
- Correct Plug Engagement — dual 16 mm and 19 mm sizing matches the specific spark plug hex dimensions found across the GX25, GX35, GX50, HHT25, and WX10 product range, eliminating the rounding risk that comes with an ill-fitting socket
- Genuine OEM Tool — sourced directly from Honda, this is the same wrench Honda technicians use; no guessing whether an aftermarket socket will clear the plug recess on these small-displacement engines
- Broad Compact-Unit Coverage — listed for Honda's mini 4-stroke horizontal shaft engines, the HHT25 trimmer, and the WX10 water pump, making it a single tool that covers multiple pieces of compact Honda equipment
- Serial-Range Awareness — Honda periodically updates service tools at production breaks, so confirm your unit's serial number against the compatibility table to ensure part number 89216-VJ3-J10 is correct for your specific machine
A plug wrench is a spark plug removal and installation tool sized precisely to the hex of the plug it is built for. On Honda's small-displacement engines and compact equipment — where tight clearances around the plug boss make a standard deep socket awkward or unusable — having the right wrench prevents thread damage, cracked ceramic insulators, and under- or over-torqued plugs. Using an incorrect tool on these compact units risks damaging the plug or the cylinder head threads, turning a routine service task into a costly repair.
