Product Features
- High-Flow Synthetic Safety Media & Ultimate Engine Protection: Serves as a inner safety barrier nested within the primary air filter assembly. Built with high-porosity flame-retardant synthetic media that maintains negligible airflow resistance under normal loads, while guaranteeing 100% dust interception into the engine manifold during primary filter replacement or primary element damage.
- Reinforced Structural Cage & Anti-Collapse Design: Engineered with an ultra-rigid thermoplastic and electro-galvanized mesh support cage designed to withstand severe intake vacuum pressures from high-displacement engines (C13/C15/C18). Prevents structural deformation or filter media collapse even under high pressure differentials caused by wet, heavily loaded primary elements.
- Radial-Seal Elastomeric Interface for Leak-Free Lockout: Integrates a precision-molded, high-resilience polyurethane radial-seal gasket. Creates a 360-degree, vibration-proof air-tight lock upon installation against the air cleaner housing tube, effectively eliminating dust bypass without requiring manual bolt-clamping forces.
