do88 BigPack Intercooler & Pipe Kit - VW Polo GTI (AW) / Audi A1 40TFSI

The do88 BigPack is arguably the best performance intercooler kit on the market for the VW Polo GTI (AW) and Audi A1 40 TFSI (EA888)[cite: 296]. This complete package combines the do88 performance intercooler with a full high-flow pressure pipe kit, replacing everything between the turbo outlet and the throttle body for maximum performance[cite: 297, 310].

Designed for those with high horsepower goals who refuse to compromise, this kit delivers a huge improvement over the stock setup[cite: 298]. While upgrading the intercooler alone offers significant gains, pairing it with the pressure pipe kit unlocks the full potential of your engine[cite: 299].

Configuration Options

This BigPack is available in two versions to match your engine generation. Please ensure you select the correct version based on your vehicle's production date:

• Version 1 (EA888 EVO3): For cars with a production date up to approx. 04.10.2021.
• Version 2 (EA888 EVO4): For cars with a production date after approx. 04.10.2021.

Performance Stats

Verified by tests in our SuperFlow SF-1020 flow bench, the do88 BigPack delivers clear advantages over the OEM intercooler and pipes[cite: 300, 301]:

• Larger Core Volume: 8,490 cm³ vs OEM 6,376 cm³ — a 33% increase! [cite: 302]
• Massive Cooling Area: 1,198 cm² vs OEM 797 cm² — a 50% increase in active cooling area! [cite: 303]
• Improved Airflow: Flows 253 CFM @ 0.15 bar pressure drop vs OEM 224 CFM — a 13% increase! [cite: 304]

Quality Construction

The kit features a performance intercooler with an all-aluminium construction and CAD-designed, flow-optimized cast end tanks[cite: 311]. It is paired with 2.5” (63mm) mandrel-bent seamless aluminium pressure pipes and custom high-quality silicone hoses reinforced with 4 layers of polyester/aramid fabric[cite: 312].

Methanol Injection Ready: The pressure pipe is equipped with a CNC-machined 1/8 -27 NPT connection, perfect for methanol injection. (Delivered with a blanking plug) [cite: 305, 306].

Note: Only after an engine software tune will the do88 BigPack provide a performance increase over the OEM intercooler, as the OEM unit is designed for standard power levels[cite: 315].
