Nope, actually it's a water tank, for circulating water (ice water during race events) to the intercooler under the hood. Helps cool the intake charge since physics dictate that compressing air automatically creates heat as a byproduct. Normally supercharged cars will have a small 1 gallon tank under the hood, but this 8 gallon tank helps me have cooler water, or use ice water for longer periods of time before the water gets hot.
