This interchiller system uses your car’s air conditioning refrigeration system to chill the intercooler fluid. This increases the efficiency of your air to liquid intercooler and provides cooler, denser air to the engine. Better air flowing to the engine means you can reduce knock retard, make more horsepower and experience reduced heat soak. Even on hot days when your external engine temperature is well over 200 degrees Fahrenheit, you’ll be able to reach down and comfortably lay your hand on the intercooler inlet at the front of the engine. It will be cool/slightly cold, making it clear your intercooler is functioning on a completely different level than it did before adding the interchiller.
ATS-V intercooler systems only contain 3.3 quarts of fluid. You can increase the overall efficiency by adding capacity. One way to do this is coil up a couple extra loops of heater hose behind the bumper during your installation. This won’t be easy to bleed though, so you might want to consider adding some heater hose T-fittings at the top of each loop as bleed points. Another way to increase efficiency is to run a higher percentage of water in your intercooler circuit, provided you drive in a climate where you can get away with this.
Even with the boost cranked way up on our own ATS-V, IAT2 (post intercooler temperature) is only a few degrees above IAT1 (pre intercooler temperature).
Kit includes everything you need for installation, except a for a few feet of ¾” heater hose and a fuse tap (for the Drag Racing Option). Installation takes a few hours, and is not difficult. On ATS-Vs the front bumper must be removed. After installation, you will need to recharge the system with R-1234yf refrigerant, or use some adapter fittings to convert over to R-134a.
Note: We recommend using the proper cooling system port adapter (part number GE-47716-30A) to bleed and fill your intercooler. This adapter is readily available online for approximately $200.
