Product Description

The Secret Weapon Intake is designed to dramatically increase air intake volume and efficiency by utilizing a dual velocity profile—two distinct air streams, one traveling faster than the other—to deliver up to three times more air than conventional intake systems. Constructed from high-quality 6061 aluminum and precision-bent on our automated CNC mandrel bender, the intake pipe is finished to show-quality standards. Customers can choose between a brilliant Polished mirror-like surface or a sleek Stealth Black matte finish. The SW1 air filter features a tuned velocity stack that boosts airflow velocity while reducing turbulence, paired with open-pore, high-density reusable foam for long-lasting performance. Backed by a 1 Million Mile Limited Warranty and covered under USA Patent #7,263,961B2, this intake is available for over 250 applications across cars, trucks, and SUVs.
