Troubleshooting & FAQ
How do I know if this air filter fits my Yanmar engine?
This filter is designed for the Yanmar 1GM series. To ensure compatibility, please check your engine's model number against the list in the "Engine & Model Compatibility" section. Also, verify that your existing part number is an equivalent to 128170-12540 or 128171-12540.
