Specs At A Glance

Good To Know

Q: How often should these filters be replaced? A: Most heavy-duty trucks follow a service interval based on mileage or dust exposure, and checking the filter at each oil change is a practical habit. Replace when the media shows heavy loading or visible damage.

Q: Are these filters reusable? A: These are disposable engine air filters and should be replaced rather than cleaned and reinstalled. Swapping in a fresh filter keeps intake airflow consistent.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
