The Honda 89216-045-010 Spark Plug Wrench is a genuine OEM service tool designed for a wide range of Honda engines and power equipment, including GX22, GX25, GX31, GX35, GXH50, and GXR120 horizontal shaft engines, GXV50 and GXV57 vertical shaft engines, F220 and FG100 tillers, HHE31 stick edgers, HHT31 and UMK422 and UMK431 trimmers, and WX10 water pumps. Sourced directly from Honda, this is the same wrench Honda specifies for spark plug service on these units. Because Honda's small-displacement and mini 4-stroke engines use a plug socket size that standard tools may not reach cleanly, using part number 89216-045-010 ensures the correct fit and protects the plug and cylinder head threads during removal and installation.
Key Features
- Correct Socket Geometry — sized and shaped specifically for the spark plug specifications used across Honda's mini and compact 4-stroke engine lineup, avoiding the thread damage that an ill-fitting socket can cause
- Genuine OEM Honda Tool — supplied by Honda as the factory-specified service wrench, ensuring it works with the plug hex and plug well depth found on these engines and machines
- Broad Fitment — listed for GX22, GX25, GX31, GX35, GXH50, GXR120, GXV50, GXV57, F220, FG100, HHE31, HHT31, UMK422, UMK431, and WX10 equipment; confirm your model against the fitment table before ordering
- Serial Number Awareness — Honda periodically updates service tooling at production breaks, so cross-check your unit's serial number against the compatibility table to confirm part number 89216-045-010 is current for your machine
A spark plug wrench is the dedicated hand tool used to remove and install spark plugs in small engines. Honda's compact and mini 4-stroke engines — including the GX25, GX35, and GXH50 series — are built to tight tolerances with recessed plug wells that standard sockets often cannot seat into squarely. Using the correct wrench lets you apply controlled torque without cocking the socket, which protects the plug's hex, the ceramic insulator, and the cylinder head threads. Attempting plug service with an improperly sized or generic tool risks cross-threading, cracked insulators, or a seized plug — all of which turn a routine maintenance task into a costly repair.
