A bundle consisting of the Pierburg CWA100-3 water pump and an adapter cable to easily change out an existing CWA50 against the newer / stronger pump.
Useful especially for Audi vehicles with a standard CWA50 intercooler pump.

If the new pump (with our adapter) does not start at all you can also run it full speed all the time by snipping the adapters signal cable (gray/red).
With this mod the CWA100-3 will run at full speed as soon as it gets power.

There is currently a approx. 90-day lead time on these kits due to lack of availability worldwide.

Pierburg CWA100-3

The CWA100-3 is a successor of the CWA100-2 we are also offering. The dimensions and the weight are nearly the same.

New is the freshly designed impeller housing with slightly shorter water in and outlets and the bigger electrical connector.

This improves the handling of bigger cable diameters significantly.
Suitable for instance for intercooling in combustion engine vehicles and cooling of various systems in electric vehicles.
