Banks' huge 3-inch boost tube. Stock tube is smaller diameter with tighter bends which hurts flow. Banks boost tube is 3-inch constant diameter mandrel-bent Aluminized Steel with larger radius bends. More air allows for more fuel which means more horsepower.Banks boost tube is larger than the factory pipe and designed to work with the stock elbow and intercooler to improve airflow, and allow the turbocharger to spool up faster.Banks cold side tube has 60% greater flow area than stock tube. Produced from high-quality aluminized steel, the tube is mandrel-bent and constant diameter. This allows for quicker turbo spool. Better flowing intercooler tube improves retention of boost pressure (increases density) between turbo, intercooler, and intake resulting in maximum horsepower. Our red powder-coat finish stops before the end of the tube for better grip ensuring our 4- and 5-ply heavy-duty high-temperature silicone couplers hold tight under high-boost conditions. Spring-loaded constant tension clamps maintain a stronger grip to prevent leaks or blown boots.
