CTS Turbo is proud to announce an official release of their new K04 Turbocharger Upgrade for B7, B8 and B8.5 Audi A4/A5/ALLROAD 2.0T cars.
This unit features a full-frame K04 CHRA installed into their proprietary, in-house designed compressor cover and turbine housing. Based on the turbo which comes stock on a MK6 Golf R, this upgrade kit is made to fit directly in place of factory Borg Warner or IHI turbo found in B7 A4, B8 A4/A5/AllRoad and B8.5 A4/A5/AllRoad 2.0T.
CTS' engineers designed the compressor cover and exhaust housing to work with the larger K04 CHRA, exactly how intended. While other manufactures simply install a larger CHRA into a small factory-spec housing. Beware of these hybrid builds, they are not made to provide optimal flow for the larger turbine wheel and can lead to poor performance and premature failure.
High quality castings are CNC machined to replace your factory turbocharger and do not require any additional parts to be installed. All you need to run this K04 Upgrade is a tune for your ECU.
To make installation even easier, we supply OEM gaskets and installation hardware.
