CTS Turbo B8/B8.5 AUDI 2.0TFSI BOSS600 KIT (2009-2016)

DESCRIPTION

The long wait is over! CTS Turbo is happy to announce the release of the B8/8.5 2.0T Boss600 Kit. You now have a solution for a big turbo kit that is truly bolt-on. This kit replaces the factory turbo and is made to work with most of your installed parts. Fully compatible with any test-pipe or high-flow cat, as well as any intercooler. The kit works with factory or upgraded diverter/blow off valve. The intake kit is provided the larger big turbo needs more air flow. This kit is made to re-use your factory oil drain and coolant supply line for easy installation. All parts required for installation are included. Don't be fooled by other manufacturers putting a larger turbo into a stock housing. It is not beneficial, and that is why we made our own!
