Installation Notes

  1. Locate the air filter housing on your engine. It is typically a black plastic or metal box connected to the air intake.

  3. Carefully remove the old air filter element from the housing, noting its orientation.
  4. Clean the inside of the housing with a clean cloth or vacuum to remove any dirt or debris.
  5. Insert the new air filter element into the housing, ensuring it is seated correctly and forms a proper seal.
  6. Reinstall the housing cover and secure it with the original clips, clamps, or bolts.

Troubleshooting & FAQ

How often should I replace this air filter?

For optimal engine performance and protection, it is recommended to inspect the air filter during routine service intervals and replace it at least once a year or more frequently in dusty or harsh marine environments.

What are signs of a clogged air filter?

Common symptoms of a restricted air filter include reduced engine power, increased black smoke from the exhaust, higher fuel consumption, and sluggish engine response.

Will this filter fit a Yanmar 6CX or 4CX engine?

While primary compatibility is confirmed for 6LP and 6LY series engines, some aftermarket sources suggest this filter may also fit Yanmar 6CX, 4CX, 6HY, and 6KY series engines. We strongly recommend verifying the part number and dimensions against your existing filter before ordering, as we cannot guarantee fitment on unlisted models.

Is this foam filter pre-oiled or does it need oil?

This is a dry-type foam filter and does not require oiling. Install it directly out of the box after ensuring the housing is clean.
