Primary filter note

Outer filter note
The listed outer air filter part number is MT40049450.
Safety filter note
The listed inner safety air filter is 86982523. Do not remove the safety element for normal cleaning; replace it if dirty, damaged or oil-soaked.
Fitment note
Check the old filter, air cleaner housing label and parts book before ordering if the tractor has had an engine or intake-housing change.
Power range note
For a smaller tractor, the filter may not look dramatic, but dirt ingestion is still the killer. Dry mowing, loader work and chaff are bigger triggers than engine hours alone.
Engine airflow note
A similar horsepower rating does not guarantee the same filter if displacement or engine family changes. Use the engine data as a sanity check only.
Service note
Clean loose dust from the air cleaner housing before pulling the filter. Never run the tractor with the filter removed, even for a quick test.
New Holland Boomer 20 Air Filter FAQs
Should I order one filter or a full New Holland Boomer 20 air-filter set?
For a full parts check, separate the service element from the safety element: buy the outer/primary service element first, then buy the inner safety element only if it is dirty, damaged or due. Do not accidentally order MT40049450 when you meant the safety filter, or 86982523 when you meant the outer filter.
What should I check before ordering a New Holland Boomer 20 air filter?
If the old filter is missing, use 86555826 plus the housing measurements as a two-step check. If either the seal or cover depth is wrong, do not run it.
What order should I check the New Holland Boomer 20 air-filter elements?
Use MT40049450 to check the service element and 86982523 to check the safety element. Do not assume one substitutes for the other.
Can I ignore letters or suffixes in the New Holland Boomer 20 filter number?
Multiple numbers are useful only if each one is tied to the correct element position. Wrong element in the right brand is still wrong.
Why not stretch a dirty New Holland Boomer 20 air filter under load?
For a smaller tractor, the filter may not look dramatic, but dirt ingestion is still the killer. Dry mowing, loader work and chaff are bigger triggers than engine hours alone.
How does engine data help with a New Holland Boomer 20 air-filter check?
Use the engine details to catch suspicious listings. If a seller’s filter is for a totally different engine family or canister style, do not trust the cross-reference blindly.
Should I use engine displacement to verify a New Holland Boomer 20 filter?
A similar horsepower rating does not guarantee the same filter if displacement or engine family changes. Use the engine data as a sanity check only.
Official information note
Mistakes do happen. Air filter specs can change by year, engine, serial range, market and air cleaner housing. Check the old filter, operator manual, parts book and official newholland.com website before ordering or installing an air filter.
