Banks cold side tubes have 37% greater flow area than stock tubes. Produced from high-quality aluminized steel, the tubes are mandrel bent and constant diameter. This allows for quicker turbo spool. Better flowing intercooler tubes improve retention of boost pressure (increases density) between turbo, intercooler, and intake resulting in maximum horsepower. Our natural finish tubes give you the freedom to paint or powder-coat to your color of choice. The bead-rolled ends allow for better grip ensuring our 4- and 5-ply heavy-duty high-temperature silicone couplers hold tight under high-boost conditions.
