Nitrous Express N-Tercooler System for CO2 w/5lb Bottle (Remote Mount Solenoid)For supercharged or turbo applications where nitrous is not an option, Nitrous Express offers another alternative, the 'N tercooler'. Spraying nitrous over an air to air intercooler, can reduce air inlet temperatures dramatically. In a dyno test, a turbocharged Honda equipped with an NX 'N tercooler', increased its baseline by an astounding 52 wheel horsepower! If it makes horsepower, it must be Nitrous Express!
