K04 Upgrade Kit for 2.0L TFSI

Complete Hardware Conversion Kit for K04-064 incl. BOV Conversion

Fits Plug’n’Play for Vehicles with TFSI Transverse Engine and K03 Turbocharger

With our K04 conversion kit, all 2.0l TFSI transverse engines with K03 turbocharger can be converted to K04. The kit is so far plug and play for the installation of the turbocharger and for the necessary conversion of the diverter valve. Here only the cable has to be extended.
