The CSF Racing 8117W is the wider version of the 8117, a bar-and-plate intercooler core measuring 22 by 14 by 5.5 inches in a vertical-flow configuration, sized for R35 GT-R fitment and rated for over 2000 wheel horsepower. It uses a multi-louvered high-precision staggered fin design on both the ambient and pressure sides, hand-built using jigs and fixtures in a clean room and batch-brazed in CSF's digital vacuum brazing ovens. Every core is individually pressure tested at 120 psi, making it a starting point for a high-horsepower custom intercooler build.
