Good To Know

Q: What is the difference between primary and secondary filters? A: The primary filter captures most debris during normal operation, while the secondary safety filter protects the engine if the primary is damaged or removed during service.

Q: Can this filter be cleaned and reused? A: No, this is a dry-type filter element that should be replaced at recommended intervals, not cleaned with air or water, to maintain proper filtration efficiency.

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