VCTR Performance VW Golf GTI MK6 K04 350+ HP Turbocharger Upgrade

Overview

The K04 upgrade turbocharger is the established path for MK6 GTI owners targeting 350+ horsepower from the EA888 Gen2 or EA113 2.0T. This billet wheel K04 unit replaces the factory turbocharger with a more capable compressor — supporting the airflow targets required for serious MK6 power builds.

Why Upgrade?

• Billet compressor wheel for improved compressor efficiency over cast alternatives
• K04 specification supports 350+hp targets on tuned EA888 Gen2/EA113
• Direct replacement for the factory IS20/IS12 turbocharger
• The most common upgrade path for serious MK6 GTI power builds

Engineering Focus

Billet machined compressor wheel provides better efficiency and higher flow capacity than cast alternatives at the same compressor diameter. The K04 specification is well-mapped on the EA888 Gen2 and EA113 platform — extensive tuning data exists.
