Stainless Steel reservoir/fill tank for setting up your air to water cooling system for best performance and eliminate air in the system automatically.
A beautifully polished unit that will outlast the life of your car. The use of this product allows you to run your personalized coolant mix for your setup.  You can run distilled water with some water wetter or a small amount of coolant for pump lubrication.  Water has better heat capacity and transfer than coolant. The unit allows for full-time air bleeding of the system as the air passes through the heat exchanger it is pushed out into the reservoir. this keeps your water in pristine air-free condition for the best cooling.  Air bubbles in the system will reduce performance dramatically.
The unit comes with a bracket that mounts to your car frame for ease of installation.

Pierburg CWA150 Pump – with Audi harness
$397.95Original 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. -

GPS Audi 3.0T Thermostat full Assembly
$299.99VERSION 2 IS HERE: We made two significant changes to improve the CNC Machined Housing further. The first big change was to correct the overcooling issue that some customers (particularly in colder climates) were experiencing. If you purchase one of the original version 1 thermostat housings, please GPS, and they will ship you a retrofit kit free of charge. The second big change was moving the assembly screws to the outside of the oring grove. That thoroughly ensures the screw cannot drop into the engine block if it were ever to come loose.
