I have been researching the snow performance boost cooler. I know that the product showed great gains on supercharged applications and they make a kit for N/A also. I called and spoke to Matt. He said that on our cars we can expect between 8 to 12 Horsepower from the kit. It makes sense because the air charge will be cooler, thus making more power on hot days than we normally would. Also, the fuel milage will increase and he said the car would be able to run on regular. If anyone is interested call Matt at 719-271-5644. Tell him that Joe referred you from the Mach 1 registry for the G/P. You can check out the product over at www.snowperformance.net
