K04 Turbo Upgrade

The heart of our 1.8T turbo upgrade kit is the higher output K04 turbo, manufactured by BorgWarner Turbo Systems, the original equipment supplier to Audi and VW. NEUSPEED includes a high performance P-Chip that re-maps boost, ignition timing and air/fuel ratio functions. The rev-limiter (manual transmission) and top speed limiter are also raised. Also included are Denso Iridium spark plugs, 710N Diverter Valve, fuel injectors, and all required gaskets and hardware.


Fits: 2001-05 Audi A4 1.8T w/ Varaiable Cam Timing and 2001.5-05 VW Passat 1.8T w/ Varaiable Cam Timing. VCT equipped engines have a cylinder shaped electrical solenoid at the back of the cylinder head.

For P-Chip installation: ECU needs to be flashed by one of our dealers or sent to Neuspeed Headquarters.

The K04 Upgrade Kit is not emission-certified for highway use. If you reside in California or states that follow California emission laws, this kit is intended for off-road use only. Check your state's emission laws before installing.
