The CTS Turbo Upgrade K04 turbocharger (part number CTS-TR-1070) is designed for cases where Stage 2+ is no longer enough and the factory K04 has reached its limits. It bolts directly in place of the factory turbo on the Audi A4, A5, Allroad and Q5 2.0T of the B7 and B8 generations.

Features

  • CTS-specific K04 core, reinforced thrust bearings
  • Dedicated K04 housing, non-hybrid, purpose-built part
  • OEM or better manufacturing tolerances
  • VSR high-speed balancing
  • Direct bolt-on replacement for the factory part

Installation

Installation is recommended by an experienced tuner. An ECU tune matched to the new turbo is essential: without it, the turbo's potential will not be used and engine management will stay on the factory part's settings.
