Boost Tube Upgrade Kit Natural finish (Set)
Increases flow area up to 65% over stock
Banks’ huge 3-1/2″ boost tubes. Stock consists of a 3″ plastic cold side tube and a 2.75″ metal hot side tube. Banks boost tubes are both 3-1/2″ constant diameter mandrel bent. More air allows for more fuel which means more horsepower.
50 State Compliant:
CARB E.O. D-161-122
This kit is designed to work with the stock elbow or new Banks Monster-Ram (3.5″ or 4″) and the stock intercooler (or aftermarket intercooler with stock inlet and outlet size and location).
Works with Banks Ram-Air (Rev E or newer) and Stock Airbox. See notes in description for details.
Are you running the new bad-ass Banks Monster-Ram for the 6.7L Cummins? Banks boost tubes are larger than the factory pipe and designed to work with the stock elbow or new Banks Monster-Ram (3.5″ or 4″) which will improve airflow, and allow the turbocharger to spool up faster.
Banks hot and cold side tubes have up to 65% percent 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. Spring-loaded constant tension clamps maintain a stronger grip to prevent leaks or blown boots.

Better flowing intercooler tubes results in less boost pressure loss allowing for more air and fuel to be delivered to your engine resulting in maximum horsepower.
This kit is designed to work with the stock intercooler (or aftermarket intercooler with stock inlet and outlet size and location).
NOTE: Hot side tube will not fit with GBE Airbox older than Rev E (see notes in description). Must have OEM Airbox or Rev E GBE airbox. All airboxes prior to Rev E do not have revision label. If your GBE airbox does not have a revision label, it will not fit with the GBE OEM replacement boost tube.
