Case IH 9330 Extra Air Filter Notes
| Engine displacement | 8.3 L | 506.5 cu in |
|---|---|
| Engine horsepower | 240 hp | 179 kW |
| Primary filter note | For the Case IH 9330, the listed primary air filter part number is 1265510C1. Match the number before buying because air cleaner setups can vary by engine, serial range and market. |
| Outer filter note | The listed outer air filter part number is 932391C2. |
| Safety filter note | The listed inner safety air filter is A44804. 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 | A dirty filter on this setup can show up as reduced pull, black smoke or higher temperature. That is more useful than staring at the hour meter. |
| Engine airflow note | Engine size is useful context for service urgency, not a license to ignore the part number. The canister and seal decide fitment. |
| 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 9330 Air Filter FAQs
Should I order one filter or a full Case IH 9330 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 932391C2 when you meant the safety filter, or A44804 when you meant the outer filter.
What does the Case IH 9330 horsepower and filter size combo tell me?
Horsepower tells you airflow demand; length and outside diameter tell you rough element size. Together they say whether restriction is a service concern or mostly a fitment check.
Why should I compare the old Case IH 9330 filter before buying?
Use 1265510C1 as the anchor number, then verify the old element and housing label. This is a mixed letter-and-number part number, and the setup looks like a primary, outer and inner safety element setup, so one loose search result is not enough. The size data points to a large and deep element, so compare the removed element against both length and outside diameter before fitting.
Why can a similar-size filter still be wrong for a Case IH 9330?
The length-to-diameter shape points to a large and deep element. That helps catch obvious bad matches, but cover depth, seal compression and end-cap shape matter a lot.
How do I avoid mixing up Case IH 9330 outer and safety filters?
This looks like a multi-element setup. Keep the outer/primary service element and the inner safety element separate when ordering, because mixing up 932391C2 and A44804 is the easy mistake.
What is the biggest fitment trap with the Case IH 9330 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.
When does the Case IH 9330 air filter become a performance problem?
A dirty filter on this setup can show up as reduced pull, black smoke or higher temperature. That is more useful than staring at the hour meter.
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.
