Genuine Borg Warner K04 upgrade for the B7 A4 2.0T.

This is not a full bolt on kit. This will require tuning and fuel injectors to reach the full potential of this turbocharger.

The Borg Warner K04 is capable of supporting up to 325CHP on the B7 A4 2.0T and this is the perfect bolt on for the DIY turbo kit builder.
