Product Description

The Weapon R 710-111-102 Secret Weapon SW1 is a high-performance universal air filter designed for intake systems with a 4-inch inlet diameter. Developed through extensive testing of air intake velocity, air mass, and airspeed dynamics, this filter delivers superior airflow compared to conventional cotton gauze filters. The centerpiece is a CAD-designed and flow bench tested velocity stack (turbo velocity stack) that significantly increases airflow, airspeed, and air mass entering the engine for measurable performance gains. The high-density polyurethane foam filter media features Open Cell Technology that allows air to flow around captured dirt particles, maintaining strong airflow even as the filter accumulates contaminants. Studies show up to 80% better flow rates and improved dirt filtration compared to traditional cotton filters. The filter is fully washable and reusable with no oiling required - simply disassemble, clean the foam element, and reassemble. The gunmetal velocity stack and black foam element provide an aggressive appearance in the engine bay. Includes silicone coupler and stainless steel clamp for secure installation on any 4-inch intake tube.
