Troubleshooting & FAQ

Q: How do I know if this air filter fits my specific Yanmar engine model?
A: This filter is designed for Yanmar's 2GM, 3GM, 2YM, and 3YM series engines. Please check the "Compatible Engine Models" table on this page to confirm your exact model is listed. Verifying the part number 128270-12540 is the best way to ensure a match.

Q: Is this just a noise suppressor or a real air filter?
A: This component serves a dual function. It is designed to reduce intake noise, but it also provides essential air filtration. The paper filter element is supported by a metal mesh frame, which prevents any filter material from disintegrating and being ingested by the engine.

Q: How often should I replace this air filter element?
A: Replacement intervals depend on the operating environment (e.g., dusty or saltwater conditions) and hours of use. We recommend inspecting the filter during routine maintenance and replacing it annually or when it appears dirty or clogged to ensure optimal engine performance and protection.

Q: OEM vs. Aftermarket?
A: This listing is an aftermarket replacement part (not an OEM component). We build to OEM specifications using comparable-grade materials. Production is done in an ISO9002-certified facility, and each batch is inspected for consistent performance.

Q: How fast do you ship and how much does it cost?
A: We offer fast global shipping—typically 5–15 days worldwide—and standard shipping is free. Expedited options are available at checkout depending on your location.

Q: What is your warranty and return policy?
A: This product includes a 1-year warranty against manufacturing defects under normal use. If something goes wrong, contact our support team with your order details. Returns are accepted within our standard return window (unused & in original condition); please see our policy page or reach out for instructions.
