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. Even if there is a factory-installed intercooler, generally these stock units are not ideal even for factory boost levels. They are usually mounted in awkward locations and become very susceptible to heat saturation. They are not ideal for increased boost levels. Our vehicle specific kits include all the necessary mounts, aluminum piping, hoses, and clamps required to install the kit. All kits are designed with specific cores to provide an ideal concession of cooling and flow, with the added benefit of aggressive looks and style. This is achieved by finding an ideal position and configuration for a wide range of boost levels. Our engineers properly size the number of rows in the core and tune the internal core with either a free flowing V-spec. core, our new M-Spec. bar-and-plate core, or our R-Spec core with a different inner fin patterns . The V-spec and R-Spec cores are a lightweight air-to-air, tube and fin design with a highly efficient tube design, which allows smooth ambient flow for optimum heat dissipation and flow to engine cooling systems. Although only offered in very limited sizes, the M-Spec core is an economical compromise that has performance, which lies between the free flowing V-spec. and the extreme cooling potential of the R-Spec. cores. GReddy intercoolers kits offer a great balance of heat exchanging efficiency and flow. The ends of the cores are TIG-welded and capped off with our smooth flowing heavy-duty cast aluminum GReddy endtanks. Lightweight mandrel bent aluminum piping and/or cast aluminum elbows, complete with hose couplers, are used to route air charge smoothly to and from the intercooler.
