One of the best ways to increase horsepower on any forced-induction engine is through intercooling. An intercooler must have the ability to cool down the compressed air and deliver it to the intake manifold without loosing pressure. The free flowing intercooler will help the turbocharger at higher rpm which will provide increased horsepower. Unfortunately, it is almost impossible to place a large capacity intercooler in a limited space engine compartment. GReddy Intercoolers are designed to fit in limted spaces and maintain a high level of heat dissipation through the use of an internal fin design. GPP offers a complete line of factory replacement upgrade intercoolers along with a wide variety of custom sized units for special applications. All GReddy Intercoolers are designed with a special high-density core to give you maximum cooling with the least pressure drop. V-Spec. Core: Depending on the application and usage, some turbocharged set-ups require different flow characteristics. To add to the 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. Note: Must use with GReddy Intercooler Piping Kit. Note: Modifications required for installation.
