GDP 3.50" Intercooler Boost Tube 10-12 Dodge 6.7L Cummins

The GDP Boost Tube replaces the small factory plastic unit with a 3.50" mandrel bent pipe and new silicone couplers. The 3.50" mandrel bent tube is a perfect match to the intercooler outlet and greatly reduces restriction vs the stock plastic piping. 3.50" tubing maintains air density and velocity via uniform tubing size to eliminate air speed reductions before entering the intake manifold.
