Upgrade the factory turbocharger in your 2011-2016 GM 6.6L Duramax with the BD-Power 1046603 Compound S475 Add-A-Turbo Kit. The BD-Power Add-A-Turbo Kit adds an S475 to your stock turbocharger giving you the ability to tow heavy loads, maintain safe EGT's, and keep the factory-like turbo spool. Adding the S475 to your factory Variable Geometry (VGT) Turbocharger allows you to retain use the stock exhaust brake, while adding the extra air from the S475 to give you the flow needed for increased performance.
This Compound Turbo System has been engineered by BD-Power to provide a clean look and installation. Using key components like an enclosed cold air intake, and a dual aluminum coolant and overflow tank, make this a perfect fit under the hood of your truck. In addition, the passenger side battery will remain in the engine bay, instead of having to be removed or relocated to the bed or frame rail like some other kits on the market. Each kit includes a BD-Power passenger side up-pipe, PCV system, rotomolded MAF/humidity sensor intake, 5" air filter, 3" hot-pipe, O-ring sealed v-bands, silicone molded coolant lines, and a 4" downpipe that does not require cutting of the fender liner.
