Audi 3.0T CWA150 Upgrade Kit

This upgrade package assembled by GAS consists of a Pierburg CWA150 water pump and a plug & play wiring harness for Audi vehicles with a standard CWA50 intercooler pump. This upgrade should be one of the first cooling system mods you do to your 3.0T/4.0T!

The CWA150 is an upgrade over the CWA100-3, featuring a freshly designed impeller & housing to accommodate higher system pressures, as well as a more robust electrical connector to accept larger diameter wiring. This allows higher duty cycles to be run for extended periods of time without worrying about premature failure.

This pump retains full PWM control from the stock ECU, but can also be run at 100% duty cycle by disconnecting or cutting the grey/red signal wire in the adapter harness. This is the largest intercooler pump you can run on the 3.0T safely without wiring an external relay setup!
