This kit replaces the restrictive factory inlets ahead of the S55 twin turbochargers. It opens the inlet to 63mm against the 55mm stock section, a 33 percent larger flow area, and do88 measures 778 CFM at a 75 mbar pressure drop against 690 CFM stock, 13 percent more flow. The rear inlet is a custom aluminum pipe with a welded CNC machined turbo connection radius flange, and the front inlet is a 3D freeform steel wire reinforced silicone hose with a CNC machined radius adapter. Matte black hose clamps are included. This version is for the OEM 41mm turbochargers; do88 lists a separate version for 54mm hybrid turbos.
