This supplemental install kit is designed for consumers that purchase a Howler Performance VGT Turbo Kit (PN: 1047139, 1047136, 1047140) and have a Dodge 5.9L Cummins 2003-2005 equipped with an automatic transmission. These trucks have a factory cooling system tube that goes under the manifold and interferes with the turbo mounting flange of the Howler manifold. This kit re-routes the coolant tube up and over the exhaust manifold to ensure proper clearance for the turbo.
