Troubleshooting & FAQ
How do I know if this filter fits my Yanmar engine?
This filter is designed for Yanmar 4LH, 4PH, 4LM, 4CH, 4CHL, and specific 8LV series engines. To ensure a correct fit, please check your engine model against our compatibility table and verify that your existing part number is XN199611-01 or XN199611.
What are the signs of a failing air filter?
Common symptoms of a clogged or old air filter include a noticeable decrease in engine power, increased black exhaust smoke, and higher than normal fuel consumption. A visual inspection showing a dirty, deteriorating, or damaged foam element is also a clear sign it needs replacement.
Is this a direct replacement for the original Yanmar filter?
Yes, this is a direct aftermarket replacement for Yanmar OEM parts XN199611-01 and XN199611. It's engineered to fit and function just like the original, with no modifications required.
How often should I replace this filter?
Replacement frequency depends on your engine's operating hours and environment. As a general rule, inspect the filter every 100 hours or annually, and replace it if it appears dirty or damaged. Always consult your engine's service manual for the manufacturer's recommended service intervals.
Is there a difference between part numbers XN199611 and XN199611-01?
