DESCRIPTION
Upgrade charge-air cooling with the do88 BigPack Intercooler Kit. BIG-430-S fits Volkswagen Polo GTI 1.8T / Seat Ibiza Cupra 1.8T EA888 14‑17.
The best VW / Seat 1.8 TSI EA888 performance intercooler kit on the market!
This BigPack includes both the do88 performance intercooler and pipe kit.
This kit is for those with high horsepower goals who want the absolute best! Upgrading to our performance intercooler alone provides a significant improvement, and when combined with the pressure pipe kit, the performance gains are even greater. Our pressure pipes offer considerably better airflow than stock piping, verified by multiple in-car tests and do88’s SuperFlow SF-1020 flow bench.
Advantages with do88 BigPack (OEM intercooler/pipes):
- Core volume: 8,767 cm³ (OEM 4,763 cm³), 84% larger
- Active cooling area: 1,753 cm² (OEM 595 cm²), 194% larger
- Airflow at 0.15 bar / 2.18 psi pressure drop: 264 CFM (OEM 232 CFM), 14% higher
- Pipe includes one methanol injection connection (1/8-27 NPT), delivered with blanking plug
Optional upgrade:
You can choose to add the upgraded do88 Turbo Muffler Delete for further performance increase. If not selected, the kit remains compatible with the OE/stock turbo muffler.
The BigPack includes a full aluminum performance intercooler and a complete 2.5” pipe kit with silicone hoses. It replaces everything between the turbo outlet and throttle body, providing a dramatic improvement in airflow and cooling performance.
The do88 intercooler features all-aluminum construction, CAD-designed, flow-optimized cast end tanks, and an optimized core design for maximum cooling efficiency with minimal pressure drop.
The pressure pipes are 2.5” mandrel-bent seamless aluminum, with custom high-quality silicone hoses reinforced with four layers of polyester/aramid. These hoses 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 the OEM intercooler’s capabilities. After an engine software tune, the do88 BigPack provides a clear performance improvement.
do88 BigPack comes with all necessary installation hardware.
