Key Features
- Genuine Honda OEM — sourced directly from Honda, this Oil Filler Extension meets the same specification as the part that left the factory with your engine, ensuring correct thread engagement and sealing at the filler port.
- Fits GXV50 and GXV57 Engines — designed specifically for GXV50 and GXV57 vertical shaft engines; check your engine serial number against the fitment table to confirm the correct application.
- Proper Oil Access — a correctly fitted oil filler extension keeps the fill point accessible and properly sealed, helping maintain oil level accuracy and preventing contamination during servicing.
The oil filler extension is a tube or neck that connects to the engine's crankcase, extending the oil fill opening to a more accessible position on the engine. It allows an operator to add or check oil without obstruction, and its seal keeps contaminants out of the lubrication system. When this component is cracked, missing, or improperly fitted, oil can be underfilled or contaminated, leading to accelerated engine wear and potential engine damage.
