There is currently an approx. 90-day lead time on these kits due to a lack of pump availability from Pierburg Germany. If you are able to add this to your cart it means we have them in stock ready to ship, likely in limited quantities, or we have an order on its way already with a pre-set allocation of pumps available. If you have any questions regarding when you can expect to receive your pump don't hesitate to reach out to us first!

This upgrade package consists of a Pierburg CWA100-3 water pump and a specific plug & play wiring adapter for Audi vehicles with a standard CWA50 intercooler pump. At 50% more flow and half the price of the factory Audi pump, this upgrade should be one of the first cooling system mods you do to your 3.0T/4.0T!

The CWA100-3 is an upgrade over the CWA100-2, featuring a freshly designed impeller housing with a slightly shorter water inlet and outlet, 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!
