This torque booster tube is the perfect upgrade to convert the Stage 1 intake system (P/N: 51/54-12111) into a Stage 2 intake system. It replaces the stock intake tract with a 3 1/2" wrinkle-black powder-coated, mandrel-bent aluminum tube.
Tuned Length induction: This torque booster tube uses a split-tube design with a mitered transition that allows the twin turbos to equally share the increased airflow. This design decreases turbulence and increases velocity resulting in increased horsepower and torque.
Hassle-Free Installation: The torque booster tube connects directly to the 3-angle filter adaptor on the Stage 1 system and comes with all new couplings and clamps for a quick and easy installation.
*Note: This torque booster tube is not CARB exempt at this time and is not legal for sale in California or use on vehicles registered with the California Department of Motor Vehicles.
NOTE: This tube will not work with the 2011 Stage 1 system (PN 51/54-12061)
