Banks Power 3.5-inch constant-diameter boost tubes upgrade the 2013–2018 Ram 2500/3500 6.7L Cummins intercooler plumbing, increasing flow area substantially over the stock 2.75" tubes. Mandrel-bent, aluminized steel construction and larger-radius bends improve airflow and turbo spool characteristics. The kit includes red powder-coated tubes, heavy-duty silicone couplers and spring-loaded clamps for secure sealing under boost.
