do88 pressure-pipe kit for Volvo models with the 3.0 T6 engine, designed for modified engines and improved airflow.
On a SuperFlow SF-1020 flow bench, the do88 kit measured 498 CFM at a 0.1 bar / 1.45 psi pressure drop, compared with 436 CFM for the standard pipes — a 14% improvement.
The pipes are made from 70 mm / 2.75 inch mandrel-bent seamless aluminium. The custom silicone hoses use four layers of polyester/aramid reinforcement and are designed for high temperature and pressure.
The kit includes: - 2 aluminium pressure pipes, - 4 silicone hoses, - 8 standard hose clamps.
The manufacturer states that the performance benefit over the standard components is realised after an engine software tune.
