This do88 kit replaces the restrictive factory turbo inlet ducting on the 991.2 Carrera with 3 inch mandrel bent aluminum pipes and wire reinforced silicone hoses. do88 measures a 48% larger overall inner diameter than the original equipment ducting, which raises the air mass reaching the turbochargers and cuts intake vacuum restriction, rising to 66% on cars running hybrid turbos. The stainless steel wire reinforcement keeps the silicone from imploding under vacuum, and the smooth bore reduces inlet air temperature. This version carries the CNC machined adapters sized for the original equipment turbochargers.
