CSF Twin Intercooler Set for Porsche 991 GT2 RS

The CSF 8166 Oil Cooler is crafted for 1974-1989 Porsche 911/930 Turbo models, offering a direct-fit left fender upgrade. Its 50mm, 15-row tube-and-fin core with square fin design boosts cooling by ~10% over OEM (930 207 053 02/04), with no pressure drop. TIG-welded with wide-mouth fittings, it’s a drop-in fit with slotted mounts for easy retrofitting (1965-1973 with adapter kit 10 0201 053). Made in the USA, it’s ideal for street or track, includes hardware, and suits high-horsepower builds.
