GAS Divorced Cooling system reservoir B8/B8.5 S4

Currently back ordered!!!!

As of 2024, all of our kits will now include an upper bleeder port for direct connection to compatible heat exchangers! This small change means that you can continue to enjoy the benefits of a self-bleeding HX. If your HX is not self-bleeding, this port can be capped.

Audi’s supercharged V6 is a powerhouse when tuned properly, but the cooling system remains a restriction to how much power can be made before the heat takes over. Even with the addition of heat exchangers and additional reservoirs, the cooling system for the supercharger system relies on hot engine coolant as its source. 

Our upper coolant reservoir was introduced in 2017 to divorce your vehicle's cooling systems, providing your supercharger with its own dedicated coolant circuit. Now its newest revision is in full production and available for installation into your B8.5 S4/S5! 

Features

• Simple installation (under 1 hour)
• Reduces initial and sustained supercharger system temperature, resulting in lower air intake temperatures
• Can be installed on a completely stock or fully upgraded cooling system
• No cutting or drilling required, no self-drilling/self-tapping hardware
• All installation hardware & stainless clamps included
• Eliminates heat transfer from the engine’s cooling system 
• Best bang for buck cooling upgrade for the 3.0T, and an aesthetic improvement to any 3.0T’s engine bay! 

Installation instructions can be now found here!

Due to headlight differences, if you have a pre-facelift B8 S5 3.0T, you will require a B8.5 kit. If you have any questions about which reservoir kit you will need, email sales@garageautosports.com and we will be happy to help!
