Case IH STX380QT Air Filter FAQs
What should I buy for a full Case IH STX380QT air-filter service?
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 A194052 when you meant the safety filter, or A194052 when you meant the outer filter.
What would make a Case IH STX380QT air filter cross-listing suspicious?
Use P822768 as the anchor number, then verify the old element and housing label. This is a letter-prefix part number, and the setup looks like a primary, outer and inner safety element setup, so one loose search result is not enough.
Does engine power change how I service the Case IH STX380QT 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.
How should I read the Case IH STX380QT air-filter number?
The primary number format is a letter-prefix part number, while the page also has separate companion numbers. That is exactly where copy-paste ordering mistakes happen.
How do the Case IH STX380QT outer and primary filters differ?
This looks like a multi-element setup. Keep the outer/primary service element and the inner safety element separate when ordering, because mixing up A194052 and A194052 is the easy mistake.
What is the risk with Case IH STX380QT air-filter cross-refs?
The cross-ref is helpful for aftermarket shopping, but the primary number and old element should still carry more weight.
Why should I check the engine before ordering a Case IH STX380QT air filter?
Power class is useful for deciding how aggressively to inspect in dusty work. It is not enough to choose a cross-reference filter.
Official information note
