For supercharged or turbo applications where nitrous is not an option, Nitrous Express offers another alternative, the N-tercooler. Spraying CO2 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!.
