The CTS Turbo intake system relocation kit is designed for the N54 platform and is compatible with CTS Stage 2 and Stage 2+ turbocharger upgrades. It can also be used with most other upgraded turbochargers with 2-inch inlets.
The kit moves the coolant expansion tank and vacuum reservoirs to the left-hand side of the engine and creates a more direct and efficient intake path to the turbochargers. It includes all the components required to replace the restrictive original turbo intake pipes: high-flow air filters, relocation brackets for the coolant expansion tank and power steering reservoir, the required vacuum and coolant hoses, a wiring harness extension for the coolant level sensor, and stainless steel pipes.
The kit is required for the correct installation of CTS Stage 2 and Stage 2+ turbocharger upgrades, as it enables their use with 2-inch inlets.
