DESCRIPTION
Upgrade charge-air cooling with the do88 BigPack Intercooler Kit. BIG-440-2-S fits Volkswagen Polo GTI 2.0T / Audi A1 Sportback 2.0T.
The best VW Polo GTI AW / Audi A1 Sportback 40 TFSI EA888 performance intercooler kit on the market!
This BigPack includes both the do88 performance intercooler and pipe kit.
This kit is designed for drivers with high horsepower goals who want the absolute best! Installing the performance intercooler alone provides a major improvement, and combined with the do88 pressure pipe kit, the gains are substantial. Our pressure pipes offer considerably better airflow than stock piping, verified both in-car and on our SuperFlow SF-1020 flow bench.

- Core volume: 8,490 cm³ (OEM 6,376 cm³), 33% larger
- Active cooling area: 1,198 cm² (OEM 797 cm²), 50% larger
- Airflow at 0.15 bar / 2.18 psi pressure drop: 253 CFM (OEM 224 CFM), 13% higher
- Pipe includes one methanol injection connection (1/8-27 NPT), delivered with blanking plug
Available Versions:
1. Customized for EA888 EVO3, compatible with cars produced up to approximately 04.10.2021.
2. Customized for EA888 EVO4, compatible with cars produced after approximately 04.10.2021.
The BigPack includes a full aluminum performance intercooler and a complete 2.5” pipe kit with silicone hoses. This setup replaces everything between the turbo outlet and the throttle body, dramatically improving airflow and cooling performance.
The do88 intercooler features all-aluminum construction with CAD-designed, flow-optimized cast end tanks and an optimized core for maximum cooling efficiency and minimal pressure drop.
The pressure pipes are 2.5” mandrel-bent seamless aluminum. Custom high-quality silicone hoses with four-layer polyester/aramid reinforcement handle high temperatures and pressures reliably.
Always remember that the OEM intercooler was designed for the original power level. Increased power or aggressive driving may exceed OEM capabilities. Only after an engine software tune will the do88 BigPack deliver measurable performance gains over the OEM intercooler.
do88 BigPack comes with all necessary installation hardware.
