Extended Description

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, 5-bar fuel pressure regulator, coolant temp switch and all required gaskets and hardware.


Fits: 1997-00 Audi A4 1.8T and 1998-01.5 VW Passat 1.8T. For engines without variable cam timing.

For P-Chip installation: ECU needs to be 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.
