do88 charge pipes replace the OEM plastic charge piping on the 2.5 TFSI Audi RS3 and TT RS. The hot side is 70mm (2.75") mandrel-bent aluminum with a black powder coat, the cold side is cast aluminum running from the intercooler to the throttle body, and four-layer reinforced silicone hoses connect them. do88 flow testing shows 638 CFM at 150 mbar against 440 CFM stock, roughly 31% more. This OEM-intercooler version uses 70mm hose connections and includes a BOV recirculation hose, black silicone hoses, and two 1/8 NPT ports for water/methanol injection or sensors.
