do88 BigPack VW Polo GTI, Seat Ibiza 1.8 TSI EA888

The do88 BigPack VAG 2.0 TSI EA888 Gen4 (BIG-340) is the ultimate intercooler and charge pipe upgrade for high-performance VAG vehicles. Designed for serious power goals, this complete kit dramatically improves airflow, cooling efficiency, and throttle response compared to the restrictive factory system.

Key Performance Advantages

• 75% Larger Core Volume: Massive 15,811 cm³ core volume compared to the OEM 9,056 cm³ for superior heat dissipation.
• Increased Cooling Area: Active cooling surface increased by 7% for improved efficiency under sustained load.
• 36% Higher Airflow: 332 CFM at 0.15 bar pressure drop versus 244 CFM on the factory setup.
• Proven Power Gains: Up to +12 hp and +14 Nm torque measured on a VW Golf GTI Clubsport Edition 45.
• Lower Intake Temperatures: Post-intercooler air temperatures reduced by up to 12°C under identical conditions.

All-Inclusive BigPack Solution

This BigPack combines a full aluminium performance intercooler with a complete 2.5” charge pipe kit, replacing everything between the turbo outlet and throttle body. The result is a drastic improvement in airflow, reduced pressure drop, and consistently lower intake temperatures.

Performance Intercooler

All-aluminium construction with CAD-designed, flow-optimised cast end tanks and a high-efficiency core for maximum cooling with minimal pressure loss.

2.5” Charge Pipe Kit

Mandrel-bent seamless aluminium pipes with reinforced silicone hoses, delivering significantly better airflow than the restrictive factory piping.

Engineering & Build Quality

• High-Flow Pipe Design: Verified through in-car testing and SuperFlow SF-1020 flow bench measurements.
• Methanol Injection Ready: Integrated 1/8-27 NPT methanol injection port with supplied blanking plug.
• Reinforced Silicone Hoses: 4-layer polyester/aramid construction rated for extreme temperature and pressure.

Compatibility & Applications

Designed for VAG vehicles equipped with the 2.0 TSI EA888 Gen4 engine, this BigPack is ideal for tuned or hard-driven cars where the factory intercooler becomes a performance bottleneck.
