If you didn't already know AFCO currently makes the best selling and best performing heat exchanger for the 2003-2004 Mustang Cobra. When dealing with Roots or Twin Screw Superchargers there's always the issue of intake temps. When running the car hard and spinning the blower fast you create heat. Heat equals a loss in power as well as the possibility of damage to the engine. One way to help reduce these intake temps and the risk of damage is to add more fluid into the intercooler system which in turn helps lower intake temps by dissapating heat. Whether it be on the street or at the track the warmer the car runs the more timing gets pulled. In addition to that an excessive amount of heat known as heat soak starts to take place. This keeps the car down on power and running less efficient. This again can be helped by adding more fluid into the cooling system. The temperature of the intercooler fluid will lower and cool down faster in between runs.
