Weapon-R Intakes are CNC Mendrel Bent out of 6061 aluminum, and are flow tuned to match every engine application to maximize engine output. All Colored Weapon-R intakes are now Powdercoated and have tigwelded fittings for a sure seal. To increase intake charge, we developed the Dragon Filter, which features an internal tuned flow velocity stack design and Air Turbulance guides to maximize gains. Weapon*R uses the highest quality High Flow 4PLy Poly Urethane Foam to ensure a protected high performance engine. Many studies have shown Higher flow & Better Dirt Filtration with Foam Filter and the conventional cotton filter. Flow rates of up to 80% more Air, which increases your engines performance.
