| 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. |

Case IH CVX 170 Air Filter FAQs
What is the safest way to match a Case IH CVX 170 air filter?
If the old filter is missing, use 87420283 plus the housing measurements as a two-step check. If either the seal or cover depth is wrong, do not run it.
How do I avoid mixing up the Case IH CVX 170 air-filter elements?
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 381423R92 when you meant the safety filter, or A189348 when you meant the outer filter.
Should I buy separate outer and primary filters for a Case IH CVX 170?
The outer filter is the dirt-catcher; the inner filter is the backup. Service them with different expectations instead of replacing both out of habit.
What part-number mistake should I avoid on a Case IH CVX 170?
The part-number pattern can help spot junk listings. If a seller’s number looks nothing like the catalog style, verify it against a real drawing.
Can the Case IH CVX 170 lose power from a dirty air filter?
This is a higher-airflow class, so restriction matters fast. If it is working in dust, inspect before the 400-hour planning mark instead of waiting for visible power loss.
Why combine Case IH CVX 170 displacement and horsepower when checking filters?
If a cross-reference is for a different displacement family, verify it hard before buying. Similar model names can hide different intake setups.
What mistake ruins the point of the Case IH CVX 170 safety filter?
Do not treat the safety filter like a second primary filter. It should stay protected; once it is dirty, replace it instead of trying to revive it with air pressure.
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.
