GReddy V-Mount Intercooler & Radiator V2 Kit for Mazda RX-7 FD3S

GReddy V-Mount Intercooler & Radiator V2 Kit for Mazda RX-7 FD3S Specifications

Specially designed for the Mazda RX-7 FD, this V2 GReddy V-mount kit improves engine performance by lowering water and charge air temperatures, taking advantage of a configuration inherited from racing. By placing the radiator and intercoler in a V layout at the front of the engine bay, cooling is enhanced by a direct supply of fresh air, which is channelled to make the most of its capacity. This layout is ideal for RX-7s tuned for track use or drifting, where cooling management is a key factor in performance and reliability.

Compared to the first version, this kit has been improved by taking a number of points into consideration. For example, the angle of the radiator has been defined to maximise the velocity of the airflow and the piping configuration has been optimised for ventilated bonnets. In addition, plates have been fitted to the radiator and intercooler to guide the air and prevent it escaping through the bumper openings. Available as part of the full kit, the air filters have been positioned as far forward as possible so as not to be overly affected by the heat from the engine.
