Product Description

Borg Warner SX K04 Turbocharger Audi 2.0 TFSI Upgrade

The electrical recirculation valve, which is also integrated into the compressor casing, guarantees fast response times when closing the throttle valve. The use of a ''latest generation'' turbine wheel helps increase the efficiency of the turbocharger significantly, while optimized thermodynamics have led to further improvements in fuel consumption and transient behavior, i.e. the acceleration of the engine at full throttle. The K03 original replacement turbo has electronic pop-off valve integrated into compressor housing, the K04-064 upgrade turbo has not. Upgrade turbo does not come with a compressor recirculation valve or the mounting detail for one. An external valve will have to be used. External pop-off valve has to be fitted. Moreover, K04-064 has a larger compressor housing discharge.
