Enhance airflow even further on your Banks Power 3.5" or 4" Monster Ram equipped 2007.5-2009 Dodge Ram 6.7L Cummins with the Banks Power 25991 Cold Side Boost Tube Upgrade Kit. This driver side Boost Tube features 40 percent greater flow area than the stock tube, increasing performance by allowing for a quicker spooling turbo while reducing EGT's. Constructed of mandrel bent 3.5" aluminized steel, this tube dwarfs the factory 2.7" tube and installs perfectly in its place. Included with the Boost Tube are heavy-duty silicone couplers and spring-loaded constant tension clamps that can withstand high temperatures and hold tight under high-boost conditions. Bank's applies a red powder coat finish that stops before the end of the tube for better coupler grip.
