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 undersized 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, 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. Our engineers properly size the number of rows in the core and tune the internal core with either a V-spec. core or with a different inner fin pattern in the R-spec core. All cores are of a lightweight air-to-air, tube and fin design. The high efficiency tube design allows smooth ambient flow for optimum heat dissipation and flow to engine cooling systems unlike typical heavy bar and plate types that disturb ambient flow like a wall, or wing shaped tubes types which flow ambient air so fast there is little time for heat transfer. GReddy intercoolers offer the perfect 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 end-tanks. Light-weight 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.

V-Spec. Core

Depending on the application and usage, some turbocharged set-ups require different flow characteristics. To add to our tuning choices, GReddy developed the V-spec. line of intercooler cores with an inner "Micro Grove Tube" design. This design was developed to allow for larger cores that give good cooling with a more free flowing internal core. This is ideal for applications with low to medium-high boost levels in factory turbocharged engines or normally aspirated engines with bolt-on turbo kits.

R-Spec. Core

GReddy R-Spec. cores feature a high heat-dissipating "Inner fin" design. This is ideal for medium to high boost levels on higher horsepower or upgraded turbo engines. The larger internal surface area provides superior cooling efficiency for radiating excessive heat and minimizing heat soak. Some R-spec. kits are labeled "HG" or High Grade; these kits feature piping and end tanks that have been hand-polished to a mirror finish for the ultimate in show quality aesthetics.
