Troubleshooting & FAQ
How do I know when to replace my engine's air filter?
Check for visible dirt, damage, or deformation of the foam. A drop in engine performance, increased smoke, or reduced fuel economy can also signal that the filter is clogged and requires replacement.
Can I clean and reuse this foam filter?
For optimal performance and engine protection, it is recommended to replace the filter rather than cleaning it. Over time, foam can degrade, and cleaning may not remove all microscopic particles, reducing filtration efficiency.
What happens if I use the wrong size air filter?
An improperly fitting filter can allow unfiltered air and contaminants into the engine, leading to premature wear and potential damage. Always verify the part number and compatibility with your engine model.
What is the difference between this and a genuine Yanmar filter?
Our aftermarket filter is designed to meet or exceed OEM specifications for fit, form, and function. It offers a comparable performance and filtration level at a more competitive price point.
