Verify the engine serial number and air-filter assembly before installation. Volvo Penta D12 and D16 engines can use different early/late air-cleaner configurations, filter inserts, brackets, collars, and covers even within the same engine family.
When This Part Needs Replacement
Replace the cover if it is cracked, distorted, badly corroded, damaged at the mounting points, or can no longer be secured correctly over the air-filter assembly. A damaged or poorly fitting cover should also prompt inspection of the filter housing, bracket, collar, and mounting hardware.

This cover belongs to a specific Volvo Penta air-cleaner arrangement, so matching by shape alone can be misleading. The important checks are the air-filter assembly number, engine serial number, and whether the engine uses the applicable early or late air-cleaner configuration.
