GReddy/Trust Intercooler Aluminum Piping Kit For Nissan Skyline R32 GTR 12020901

Factory rubber intercooler piping on the R32 Skyline GT-R is prone to expansion under boost, leading to pressure loss, inconsistent boost delivery, and reduced efficiency. The GReddy/Trust Intercooler Aluminum Piping Kit (part number 12020901) replaces the soft factory hoses with rigid polished aluminum pipes and high-quality silicone couplers, creating a more stable and efficient charge-air path for the RB26DETT.

The kit features cast aluminum piping with a consistent 72 mm inner diameter and 80 mm outer diameter, designed to work with intercoolers that use 80 mm inlets and outlets. Aluminum construction resists expansion under high boost while also offering better heat dissipation than rubber. The complete package includes four polished pipes, eight GReddy blue silicone couplers, and sixteen hose clamps for a professional installation. It is an ideal companion to GReddy front-mount intercooler systems. Note that vehicles equipped with a GReddy intake plenum will require the optional adapter (part number 13920400).

At Terra Firma Automotive, we supply this genuine GReddy/Trust Aluminum Piping Kit as a practical upgrade for R32 GT-R owners seeking more consistent boost control and improved durability. Whether you are installing a larger intercooler or simply eliminating the weak points of the factory rubber system, this kit delivers reliable performance and a clean under-hood appearance. Choose Terra Firma Automotive for authentic Japanese intercooler components engineered for the RB26DETT.
