The factory intercooler on the R34 GT and GTT RB25DET is one of the first components to become a bottleneck as soon as boost levels increase. The GReddy Intercooler Kit Spec LS (12020488) is a lightweight, high-value upgrade that strikes the perfect balance between performance and affordability. Featuring a 600 x 284 x 66mm core and high-quality 2-ply silicone hosing, this front-mount intercooler dramatically reduces intake air temperatures, improves charge air density, and delivers noticeable gains in power and throttle response for both stock and mildly modified RB25DET engines.
Positioned as the “Light Spec” in GReddy’s lineup, the Spec LS offers excellent cost-performance while reducing front-end weight for better vehicle balance and handling. The kit includes all necessary aluminum piping, clamps, and hardware for a complete bolt-on installation, making it an ideal upgrade for enthusiasts looking to enhance cooling efficiency without the expense of premium Spec-R models. The result is more consistent power delivery, reduced heat soak, and improved overall engine efficiency under boost.

Whether you’re daily driving or enjoying spirited canyon runs, this intercooler gives your RB25DET the cooling support it needs to perform confidently while maintaining excellent drivability.
