The Nitrous Express N-tercooler system for CO2 with a 15 lb bottle and remote-mount solenoid offers an intercooler spray solution for turbocharged or supercharged engines when nitrous is not an option. Spraying CO2 over an air-to-air intercooler reduces inlet air temperatures dramatically; in a documented dyno test a turbocharged Honda achieved a 52 wheel-horsepower gain.
