|---|---|
| Engine horsepower | 200 hp | 149.1 kW |
| Primary filter note | For the Case IH Magnum 190, the listed primary air filter part number is AF25238. 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 190 appears to be the same listed item as the primary filter. |
| Safety filter note | The listed inner safety air filter is 87409407. 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 | Height: 16.4 in. Use dimensions as a second check, not as the only buying method. |
| Filter size note | The listed dimensions point to a long element length at 16.4 in and large outside diameter at 9.9 in. Use that as a fitment sanity check against the old filter. |
| Power range note | With a 200 hp engine class, the filter size looks reasonable for the power class, but dusty work can still load it quickly. Watch for weak pull, smoke or heat under load before waiting for the full 400-hour guide. |
| 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 190 Air Filter FAQs
What makes the Case IH Magnum 190 air-filter number risky to order blindly?
The safest match is not just the printed number. Use AF25238, then check whether the element seats fully without forcing the cover. The outer listing matching the primary means you probably do not need to buy two different outer elements.
Is airflow likely to be sensitive on the Case IH Magnum 190?
If the tractor is under load, a marginal or dirty element will matter more than it does at idle. Use the size/power combo as a reason to inspect before heavy dusty jobs.
What should I buy for a full Case IH Magnum 190 air-filter service?
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.
What do the Case IH Magnum 190 air filter dimensions tell me?
For this shape, do not eyeball it from a product photo. A close-looking element can be wrong if the seal sits at a different depth.
What is the biggest fitment trap with the Case IH Magnum 190 air filter?
The trap is assuming a large and deep 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.
Why is the exact Case IH Magnum 190 filter number important?
Use the full AF25238 string. Do not trim suffixes or ignore letters; small part-number changes can mean a different seal or element length.
Why does the Case IH Magnum 190 horsepower class matter for filters?
With a 200 hp engine class, the filter size looks reasonable for the power class, but dusty work can still load it quickly. Watch for weak pull, smoke or heat under load before waiting for the full 400-hour guide.
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.
