The factory duct between the air filter and the turbo necks down to 56mm internal diameter and carries a resonator section, both of which choke air flow. do88 replaces it with a 76mm (3 inch) outside diameter mandrel bent seamless aluminium pipe that stays full size throughout, flowing 655 CFM at 0.15 bar (2.18 psi) pressure drop against 594 CFM for the OEM pipe on do88's SuperFlow SF-1020 bench. Two custom silicone hoses with four layers of polyester reinforcement and steel wire resist heat and vacuum collapse, and four T-bolt clamps plus mounting hardware are included.
