Cross-link polyethylene filter box is engineered to specific design. It insulates and protects the filter from pulling hot air from the engine compartment, thus, increasing horsepower. Cross-link polyethylene air ducts are sculptured to give the engine a less restrictive air pass to breathe. Larger diameters, unique bends and smooth transitions gives you maximum horsepower and awesome throttle response. Cleanable and reusable high grade filter media reduces air restriction and increases engine output. Precision pleat geometry optimizes airflow throughout the intake system. High performance silicone hose connectors provides flexibility while maintains strength and thermal stability. Marine grade clamps allows optimal performance with large operating range and available for virtually any application which requires maintainability and versatility.
