Good To Know
Q: What is the purpose of the secondary or safety filter? A: The safety filter provides backup protection in case the primary filter is damaged during servicing or becomes restricted. It helps prevent debris from entering the engine during the filter change process.
Q: Are there any specific checks before installing this kit? A: Always inspect the air cleaner housing and sealing surfaces for damage or debris before installing the new filters. Proper seating of both elements is critical to prevent unfiltered air from entering the engine.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
