Honda 92-00 Civic (EX/Si) Greddy Intercooler Kit (Greddy Turbo, 31V, 12050008) Greddy Intercooler Kit: The addition of a GReddy intercooler is one of the best ways to safely increase horsepower in a turbocharged engine. By reducing the engine's inlet temperatures, a denser air charge will enter the engine; this can make more horsepower at the same boost level and even more power at higher boost levels. Greddy specific intercooler kits include all the necessary mounts, piping and hoses required to install the kit. All kits are designed with specific cores to provide an ideal compromise of cooling and flow, with the added benefit of style. This is achieved by finding an ideal position and configuration for a wide range of boost levels.
