Engine Compatibility
This air filter insert is commonly listed for Volvo Penta D4, D6, D9, and D11 diesel marine engines. Supported references include many D4 and D6 variants, along with D9 and D11 model families, depending on the exact engine configuration and serial number.
Serial Number Fitment Notice
Air filter fitment depends on the exact Volvo Penta engine model, intake housing, engine generation, and serial number. Always confirm compatibility using the engine serial number and current filter installed before ordering, especially when replacing earlier filter references.
When This Part Needs Replacement
Replace the air filter insert at the recommended service interval, when it is dirty, restricted, oil-contaminated, water-damaged, collapsed, or no longer sealing properly in the air filter housing. A restricted air filter can reduce engine performance and increase smoke, fuel consumption, and intake-system stress.
Installation Notes
Remove the old filter and inspect the air filter housing for dirt, oil residue, loose debris, or damaged sealing surfaces. Install the new insert fully seated in the housing and make sure the intake assembly is closed and sealed correctly before running the engine. Avoid running the engine with the air filter removed.

Parts Desk Insight
This filter is best matched by engine model and intake housing, not just by engine family. D4, D6, D9, and D11 references overlap, but the exact serial-number diagram and the current filter installed are the safest way to confirm the correct insert.
