Pierburg CWA150 Pump – with Audi harness
Original price was: $397.95.$379.95Current price is: $379.95.Add to cartIMPORTANT NOTES: Please update your pump fuse to 20-25 amps IF USING THE OEM HARNESS.  The best USE OF THIS PUMP IS WITH A SEPARATE ELECTRICAL CIRCUIT AND RELAY.  I do not have information on how to do this or a pre-made harness.  This would be a DIY application that you will have to research or have a trained mechanic perform for you.  Â
The CWA150 is basically the high-pressure variant of the CWA100-3 we are also offering.
The dimensions and the weight are nearly the same.
The new pumps have a new designed impeller and impeller housing to accommodate for the higher differential pressures.
It is suitable on anything that profits from that higher pressure capability to maintain consistent flow when added volume and larger heat exchangers are used. -
