The do88 turbo inlet pipe swaps the flexible factory intake on Volvo's 2.5L T5 engine for a 76mm (3-inch) mandrel-bent seamless aluminum pipe paired with custom silicone hoses built from four polyester layers and steel wire. It flows 655 CFM against 594 CFM for the OEM pipe at a 0.15 bar pressure drop, sharpening throttle response and turbo spool. The kit includes black silicone hoses, four T-bolt hose clamps, and all installation hardware.
