DESCRIPTION
Upgrade charge-air cooling with the do88 BigPack Intercooler Kit. BIG-340-1-R fits VAG 2.0T EA888 Gen4 (300+ hp).
The best VAG 2.0 TSI EA888 Gen4 performance intercooler kit on the market!
This BigPack includes both do88 performance intercooler and pipe kit.
This kit is for those with high horsepower goals who want to upgrade to the absolute best. Upgrading to the performance intercooler alone delivers a major improvement, and when combined with the pressure pipe kit the gains are substantial. The pressure pipes provide significantly better airflow than stock piping, verified by multiple vehicle tests and SuperFlow SF-1020 flow bench testing.
Advantages with do88 BigPack (OE intercooler / pipes):
- Greater core volume: 15,811 cm³ (OE: 9,056 cm³), 75% larger.
- Larger active cooling area: 2,774 cm² vs 2,587 cm², 7% larger.
- Airflow at 0.15 bar / 2.18 psi pressure drop: 332 CFM (OE: 244 CFM), 36% higher.
- Peak power gain of +12 hp and peak torque gain of +14 Nm (measured on VW Golf GTI Clubsport Edition 45, 2021, stock software).
- Post-intercooler air temperature under identical conditions: 23°C (OE: 35°C), 12°C lower.
- One methanol injection port (1/8-27 NPT), supplied with a blanking plug.
The BigPack includes a full aluminum performance intercooler and a complete 2.5" pipe kit with silicone hoses. This BigPack replaces everything between the turbo outlet and the throttle body, resulting in a significant improvement in airflow and cooling performance.
The do88 performance intercooler features an all-aluminum construction with CAD-designed, flow-optimized cast end tanks and an optimized core design to deliver maximum cooling efficiency with minimal pressure drop.
The charge pipes are manufactured from 2.5" mandrel-bent seamless aluminum pipes. Custom-made high-quality silicone hoses with four layers of polyester/aramid reinforcement are used, capable of handling very high temperatures and pressures.
Always remember that the OE intercooler is designed for the factory power level. Increased power or sustained hard driving can exceed OE performance limits. After an engine software tune, the do88 BigPack provides a clear performance advantage over the OE intercooler.
A common misconception is that only a front-mounted intercooler can deliver strong performance. In reality, the do88 BigPack outperforms many FMIC installations where limited frontal area and obstruction behind the bumper beam reduce cooling efficiency.
