cools your intercooler to -20°F at 80°F (without passing charge air). Used in conjunction with DEI or a cheaper universal one Water atomizer, my 150* intake air temps dropped to 30* and added tremendous power I turned my BMW M2 VRSF 7" aftermarket I/C into a freezer. Can handle a big boost with no time lag even with n20. and 10-lb bottle is only 20 to fill compared to 50 for a good n20
