The Honda 90203-679-000 Plug Cover Nut is a genuine OEM Plug Cover Nut designed for GD320 and GD410 horizontal shaft diesel engines. As a direct Honda OEM component, this nut is manufactured to the exact specifications required for proper fit and retention on these engines. Honda supersedes parts at serial breaks, so confirm your engine's serial number against the fitment table before ordering to ensure part number 90203-679-000 is correct for your unit. This is a straightforward hardware replacement, but using the correct OEM nut ensures proper seating and retention of the plug cover on your diesel engine.
Key Features
- Genuine Honda OEM Hardware — sourced directly from Honda, this nut matches the exact thread specification and dimensional profile required for the plug cover on GD-series diesel engines.
- Direct Replacement — installs without modification, restoring the plug cover to its correctly retained position on GD320 and GD410 engines.
- Serial Number Verification Recommended — Honda updates parts at production serial breaks; check your engine's serial number against the fitment table to confirm this is the right nut for your engine.
The Plug Cover Nut secures the plug cover on GD320 and GD410 horizontal shaft diesel engines, holding the cover firmly in place during engine operation. Without the correct nut properly torqued, the plug cover can work loose, potentially exposing the covered port and disrupting proper engine sealing. Replacing a worn, stripped, or missing nut with the correct OEM hardware restores proper cover retention and keeps the engine operating as intended.
