CSF Porsche 911 Turbo / Turbo S (991.1 / 991.2) Twin Intercooler Set

The CSF Twin Intercooler Set is the go-to intercooler upgrade for the Porsche 991 Turbo and Turbo S. It has been race-tested, data-logged and validated by some of the best Porsche tuners in the world, and offers one of the best combinations of performance and value available.

Design & Engineering

The difference is obvious at first glance: CSF's core is 115mm wide versus the factory 80mm. The high-capacity bar & plate core handles significantly more airflow and boost than the OEM tube & fin design, making it a smart upgrade for tuned cars with bolt-ons and close to mandatory for upgraded turbo builds.

The factory cores are crimped onto plastic end tanks that can crack under high boost or race-car vibration. CSF replaces them with 100% TIG-welded cast aluminum end tanks, shaped to spread airflow evenly across the whole core. The shallow OEM tanks struggle to feed the tubes at the top and bottom of the cooler.

Each intercooler is finished in an aerospace-grade, nano-particle heat dispersion coating, applied in California by a supplier to Boeing. It sheds heat roughly 35% better than raw aluminum.
