The heart of the CTS Turbo B8/B8.5 A4/A5 2.0T turbo upgrade kit for EA888 Gen 2 with AVL is the Borg Warner K04-0064 turbocharger. This turbocharger is commonly used in OEM applications such as the Audi S3 available in Europe. The highlight of this Borg Warner turbocharger in our kit is the ‘forged mill’ compressor wheel, which brings numerous benefits to the enthusiast. The technology used in the production of these turbos provides us with a variety of benefits, reduced compressor wheel weight (faster spool), increased strength, and greater surface area of the compressor wheel. Because of the ‘forged mill’ technology Borg Warner can increase the effective surface area of the compressor wheel, which results in greater air flow than conventional cast compressor wheels. 

In addition to the Borg Warner K04-0064 the CTS Turbo B8 A4 2.0T turbo upgrade kit uses a set of custom silicon hoses to relocate the factory diverter valve. Our diverter valve relocation uses the same principles as the OEM Audi S3, Audi TTS and Golf R. In addition to the diverter valve relocation our kit includes a new diverter valve housing to relocate the diverter valve, associated OEM gaskets, nuts, studs and hardware and test pipe to connect to your factory downpipe. This kit is by far the best ‘bang for the buck’ modification available for B8 enthustiasts with the 2.0T EA888 Gen 2 AVL engine.

Fitment:

  • 2009-2016 Audi A4/A5 2.0T B8 or B8.5 models

Fit supper snug!
Awesome product. I lost 2 of them on my Kawasaki Teryx 1000, and these caps fit super snug. I almost didn't think they fit because they were so tight, and had to use a rubber mallet to gentle tap them on. Worth the buy!

Happy with the price and quality!
Size: Single Slat, Color: Matte Black, Size: Single Slat, Color: Matte Black
I bought this set with low expectations to replace my OEM grill which was falling apart and getting loose. I thought, not much to lose. They actually turned out to fit and look great. Just one tip-- when installing, be sure that you are correctly positioning the tension clips to be in contact with the end of the hood notch. There are a lot of Youtube guides you can find online to help you with it. Otherwise, they will just be totally loose and not fit correctly.

Easy install !! They fit well and look good
Size: Single Slat, Color: Chrome
The grill is plastic of course but for the price it makes the car look good. I had a cracked grill and it looked so ugly. These popped right in easy install and makes the car look good again I am happy.
