The factory intercooler on the R33 GTS25T RB25DET is one of the first components to become a bottleneck as soon as boost levels increase. Mounted in an awkward location and prone to heat soak, it limits power potential and risks detonation under sustained load. The GReddy/Trust Type 24F Intercooler (12020212) is a high-performance upgrade that dramatically improves charge air cooling with its efficient core dimensions (L600 x H284 x W66mm), delivering cooler, denser intake air for stronger power output at the same boost level and even more when you turn up the wick.

Designed for use with GReddy turbo kits and intake plenums, this intercooler optimizes turbine efficiency and supports higher safe boost levels while reducing the risk of heat-related power loss. The robust construction and efficient core design make it ideal for both street and track applications, providing consistent performance when it matters most. Minor bumper reinforcement and cover modifications are required for installation, and pairing it with a GReddy intercooler piping set (sold separately) creates a complete high-flow system.

At Terra Firma Automotive, we supply this genuine GReddy/Trust Type 24F Intercooler as a premium cooling upgrade for R33 GTS25T owners seeking reliable power gains. By replacing the restrictive and heat-prone factory unit, this intercooler helps unlock additional horsepower, improves throttle response, and gives your RB25DET the cooling capacity it needs to perform confidently under boost. For enthusiasts serious about performance and engine safety, this is one of the most effective upgrades you can make to your Skyline.
