Good To Know

Q: How often should these engine air filters be replaced? A: Most heavy-duty trucks follow a set mileage or inspection interval, so check your service manual and replace when the filter shows heavy loading or restriction. Replacing all four at once keeps filtration consistent across the set.

Q: Are these original Freightliner parts? A: No, these are aftermarket engine air filters built to cross-reference OEM number 03-42776-010. Always confirm your truck's filter housing and part number before ordering.

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