The Secret Weapon Intake was designed, to increase air intake volume to the engine. The concept is to create two different air velocity profiles, one traveling at higher speeds than the other. This technology increases air volume and speed to the engine, which naturally feeds the engine 3x more air than the conventional air intake system. The intake pipe is bent out of high quality 6061 Aluminum on our Automated CNC mandrel bender. Polished to a high show quality finish. The SW1 Air filter features a tuned velocity stack to increase velocity and decrease turbulence. Only Comes In Polished. 1 Million Mile Limited Warranty Open pore high density re-usable foam Over 250 applications for Cars / Trucks / SUVs.
