Description

Banks’ 3.5″ Boost Tubes replace the factory plastic and rubber pieces that crack and split under boost on the 2011-2016 6.7L Power Stroke. They’re 40% larger in diameter than the OEM 2.5″ tubing, mandrel-bent from aluminized steel, and matched with billet venturi couplers that hold boost where the factory parts leak.

The result: quicker turbo spool, less pressure drop across the intercooler, and a setup that won’t blow apart the first time you tow heavy or chip the truck.

Pick the full kit (both sides) or just the cold side replacement if you’ve already done the hot side or just need to fix a blown cold-side tube.
