Cicio Performance 991 Turbo/Turbo S Intercooler Upgrade by CSF

We’re excited to introduce another brand new Cicio product; the Cicio 991 Turbo/Turbo S Intercooler Upgrade! Our 991 intercooler upgrade is approximately 45% larger than the OEM core. That’s an astonishing 4.5” (115mm) compared to the OEM 3.14” (80mm).


These bar and plate style cores went through extensive wind-tunnel testing and are pressure tested to 120 PSI to ensure the absolute best performance results possible.

These intercoolers were designed following 3D scanning and printing procedures to provide the most accurate drop-in fit possible. Our  intercooler is a plug and play upgrade for both 991.1 & 991.2 Turbo/Turbo S applications. These intercoolers only require slight trimming to the factory plastic upper intercooler shroud in order to make room for the 4.5” thick core. The construction of the 3D printed cast metal end tanks includes all OEM mounting pins and factory clip-in style mounting for ease of installation.

Each intercooler comes with an aerospace grade thermal dispersion coating to help provide better cooling efficiency vs the competition.
