Primary filter note
For the Case IH Magnum 370, the listed primary air filter part number is 84191182. Match the number before buying because air cleaner setups can vary by engine, serial range and market.
Outer filter note
The outer air filter for the Case IH Magnum 370 appears to be the same listed item as the primary filter.
Safety filter note
The listed inner safety air filter is 48192026. Do not remove the safety element for normal cleaning; replace it if dirty, damaged or oil-soaked.
Fitment note
Listed dimensions: Outside diameter: 9.9 in. Use dimensions as a second check, not as the only buying method.
Filter size note
The listed dimensions point to a large outside diameter at 9.9 in. Use that as a fitment sanity check against the old filter.
Power range note
This is a higher-airflow class, so restriction matters fast. If it is working in dust, inspect before the 500-hour planning mark instead of waiting for visible power loss.
Engine airflow note
The displacement helps identify the engine family; horsepower tells you how hard it breathes under load. The element still has to match the canister.
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.
Case IH Magnum 370 Air Filter FAQs
Should I order one filter or a full Case IH Magnum 370 air-filter set?
For normal service, the primary/outer element is the one that does the dirty work. The inner safety element is backup protection, so replace it less often and keep it seated while cleaning the housing.
How do I avoid buying the wrong Case IH Magnum 370 air filter?
Use 84191182 as the anchor number, then verify the old element and housing label. This is a straight numeric OEM-style number, and the setup looks like a primary/outer service element plus an inner safety element, so one loose search result is not enough. Use the listed dimension as a sanity check, but still verify the seal and end-cap style.
Which Case IH Magnum 370 air-filter measurement matters most?
One dimension is better than none, but it does not tell you the full canister fit. Check the removed element before installing.
How can part-number style help check a Case IH Magnum 370 filter?
The primary number looks like a straight numeric OEM-style number. That does not make it automatically correct, but it helps you spot obvious nonsense numbers in search results.
What order should I check the Case IH Magnum 370 air-filter elements?
For this setup, think of primary and outer as the dirty-work element. The inner safety element is not part of every quick service.
Why does airflow matter on the Case IH Magnum 370 air filter?
This is a higher-airflow class, so restriction matters fast. If it is working in dust, inspect before the 500-hour planning mark instead of waiting for visible power loss.
What is the biggest fitment trap with the Case IH Magnum 370 air filter?
The trap is assuming a large outside-diameter element is close enough because it looks right online. The seal face, end-cap depth and cover pressure have to match, otherwise dust can bypass the media.
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 caseih.com website before ordering or installing an air filter.
