TORQUE BOOSTER TUBE UPGRADE SYSTEM Black textured molded tube replaces factory intake tube and upgrades Stage 1 system Improves throttle response and improves acceleration Installs in less than 15 minutes! Increases up to 15 HP! Increases ft-lbs of torque! Reduces heat transfer to intake air! The factory intake tube often has baffles, sharp bends, and obstructions that send out flow restricting wake like pebbles in a stream. Others have constrictions in the diameter that further impede airflow. Our intake tubes feature smooth walls, gradual bends and transition chambers that straighten the airflow into the throttle body or turbo inlet. The tube is constructed of textured cross-linked molded plastic that cuts down the heat transfer from the hot engine compartment to the cold air flowing through the tube. More and more vehicles are equipped with increasingly sensitive Mass Airflow Sensors (MAF sensor) that are connected to the vehicle Engine Control Unit (ECU), the brains of the vehicle. The calibration of the MAF sensor and its position on the MAF sensor on the factory intake tube is designed to measure velocity and mass of the air flowing through the factory tube. If the velocity of the air moving over the MAF sensor is outside of the parameters programmed into the ECU, whether too fast or too slow; it will cause a lean stumble, engine error code and poor throttle response. We shape our tubes and position the MAF sensor to increase flow to the throttle body or turbo inlet while managing the velocity past the MAF sensor to keep its signal range within factory limits.
