It uses high-efficiency cellulose media to trap dirt and debris, protecting the engine from abrasive wear. The RadialSeal design creates a tight, cushioning seal without tools, making filter changes quick and secure even under heavy vibration. It is designed as a direct replacement for Fleetguard OptiAir air cleaner housings and is typically replaced as part of routine engine maintenance or when the air restriction gauge shows excessive clogging.
