The Stage 2 sealed intake system produces 14 max horsepower and 27 lbs. x ft. torque and outflows the factory intake by 16%. This radically different Stage 2 sealed cold air intake system is engineered to provide the maximum intake charge for maximum performance gains. This intake system smoothly directs increased air flow for improved volumetric efficiency and maximum performance.

360 Degree Radial Flow Air Filter: This intake is designed using a 360 degree radial flow air filter for maximum performance and filtration.  The unique oval shape allows for a lower profile housing while improving performance, turbo spool up times and throttle response.

Reduced Intake Air Temperatures:   Intake Air Temperature (IAT) at normal running speeds with this aFe intake system is 11 degrees lower than the factory intake.

Sealed Intake Design: Easily accessible with a satin black powdercoated aluminum cover, an washable/reusable conical air filter is enclosed in a molded plastic housing and mounted on a oval intake tube that smoothly supplies maximum air to the twin turbos. 

Proven Results: After a rigorous design and testing phase, the results are in. This Stage 2 sealed intake system outflowed the factory intake by 16% and produces 14 additional horsepower and 27lbs. x ft. torque.

The full effect of this system cannot be felt or tested on stationary dyno and can only be fully appreciated on the wide open highway.
