This BigPack includes the do88 performance intercooler and a complete reverse-flow pressure pipe kit. It is designed for those with high power goals who want to upgrade to the absolute best. Replacing the intercooler alone is a major improvement, but combined with the do88 pressure pipes the gain is enormous.

Key advantages of the do88 BigPack over OEM intercooler and pipes:

• Core volume: 12,302 cm³ (vs. 7,255 cm³), 70% larger!
• Air flow at 0.15 bar / 2.18 psi pressure drop: 347 CFM (vs. 204 CFM), 70% higher!
• Post-intercooler air temperature at the same conditions: 28°C (vs. 41°C), 13°C lower!
• Fits all vehicles listed below!

The BigPack replaces everything between the turbo outlet and the throttle body, dramatically improving airflow and cooling performance compared to the original system.

The intercooler is an all-aluminium construction with CAD-designed, flow-optimized cast end tanks and an optimized core design for maximum cooling efficiency and minimum pressure drop. The pressure pipes are manufactured from 2.5" mandrel-bent seamless aluminium tubing with a reversed flow design — air flowing to the throttle body is taken from the bottom of the intercooler, making the do88 pipes 550mm shorter than the OEM pipes. The silicone hoses are custom-made with four layers of polyester/aramid reinforcement — capable of withstanding high temperatures and pressures.

The do88 BigPack outperforms most FMIC installations, where only a small core front surface area is available and the unit is often partially mounted behind the bumper beam. The kit comes with all hardware necessary for installation.

The air guide to the air filter box will not fit together with these intercooler pipes. It can be fitted if you cut the hose end against the throttle body approximately 25mm.

Available hose colours: black
Throttle body diameter: 63mm / 76mm
