DESCRIPTION
Upgrade charge-air cooling with the do88 BigPack Intercooler Kit. BIG-430-S-CP-110 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 drivers with high horsepower goals who want the absolute best! Installing the performance intercooler alone provides a significant improvement, and when combined with the do88 pressure pipe kit, the gains are even greater. Our pressure pipes offer considerably better airflow than stock piping, verified in-car and on our 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 this option is 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. This setup replaces everything between the turbo outlet and throttle body, dramatically improving airflow and cooling performance.
The do88 intercooler features all-aluminum construction, CAD-designed, flow-optimized cast end tanks, and an optimized core design to maximize cooling efficiency with minimal pressure drop.
The pressure pipes are 2.5” mandrel-bent seamless aluminum. Custom high-quality silicone hoses are reinforced with four layers of polyester/aramid to 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 a measurable performance increase over the OEM intercooler.
do88 BigPack comes with all necessary installation hardware.
