CTS Turbo is proud to announce an official release of our 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 our 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.

Our engineers designed the compressor cover and exhaust housing to work with the larger K04 CHRA, exactly how intended. While other manufacturers 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.

Features:

  • CTS-spec K04 CHRA with heavy-duty thrust bearings
  • Billet compressor wheel (MFS – machined from solid)
  • K04-specific compressor and turbine housing. NOT A HYBRID!
  • OEM+ manufacturing tolerances
  • VSR high-speed balanced
  • Direct-fit factory replacement
  • OEM installation kit included
  • Compatible with any K04-specific tune
  • With supporting mods this turbo is capable of producing 350HP/340TQ on a 2.0T

Fitment:

  • 2006 – 2009 Audi A4 2.0T
  • 2009 – 2015 Audi A4 2.0T
  • 2009 – 2015 Audi A5 2.0T
  • 2009 – 2015 Audi Allroad 2.0T

Note:

  • Aftermarket High-flow catalytic converter recommended
  • K04-specific tuning required (B7 A4 required upgraded HPFP and fuel injectors)
  • Bracket on coolant line may require trimming on some models

Great buy
My dogs absolute favorite! Super durable and keeps him busy forever. The squeaker is fun but it’s nice because it’s not an easy squeak so the annoying part of it is actually tolerable. The size was perfect for my 100+lb German Shepard. I’d buy 100 more once he dominates this one.

My Dog Approves of this Toy for Agressive Chewers
My dog is a mix of a Husky and a Pit Bull. She needs to chew toys, but they usually don't last long. This one seems to be an exception. She took to it right away, and it's still in one piece pi. I assume that the bacon flavor or scent is what keeps her coming back to this toy. This one seems to be her favorite so far.

FOR SHORT TIME USE
Size: X-Small, Color: Ring Bone
My puppies love this. After a couple of weeks, it is worn so I throw it out and buy another since it's reasonably priced. I don't want them to actually ingest a chunk of this.
