Banks Power Boost Tubes for 6.7L Cummins 3.5" Mandrel Bent Constant Diameter

Banks Power Boost Tubes for 6.7L Cummins — 3.5" Mandrel Bent Constant Diameter Transform turbo response and horsepower with Banks Power 3.5" boost tubes designed for the 6.7L Cummins. Replacing the restrictive factory 3" plastic and 2.75" metal tubes, these constant-diameter, mandrel-bent tubes increase flow area up to 65% , allowing more air, more fuel, and more power. Why upgrade? Improved airflow: 3.5" constant-diameter design maximizes volumetric flow and reduces pressure drop. Faster turbo spool: Mandrel bends and smooth transitions speed response and reduce lag. Better boost retention: Higher density between turbo, intercooler, and intake for peak horsepower. Lower EGTs & improved cooling: Increased cooling capacity helps reduce exhaust gas temps. Built to perform High-quality aluminized steel construction for strength and corrosion resistance Precision mandrel bending and constant diameter for optimal flow Red powder-coat or natural finish with uncoated ends for secure grip 4- and 5-ply heavy-duty, high-temp silicone couplers Spring-loaded constant-tension clamps to prevent leaks and blown boots Compatibility: Works with stock elbow and intercooler or pair with the Banks Monster-Ram (3.5" or 4") for maximum gains. Perfect fit and finish for seamless installation on 6.7L Cummins applications.
