• Airflow at 0.15 bar / 2.18 psi pressure drop: 315 CFM (OEM: 279 CFM) – 13% higher
• Post-intercooler air temperature: 22°C (OEM: 35°C) – 13°C lower

Kit Contents

• Full aluminum do88 performance intercooler

Technical Information

The do88 intercooler is engineered using advanced CAD design with cast aluminum end tanks and an optimized core for maximum heat transfer and minimal pressure drop. The aluminum pipes improve throttle response and airflow consistency, while the reinforced silicone hoses withstand extreme boost and temperature conditions.

Why Choose the do88 BigPack?

The original intercooler is optimized for stock performance levels and can become restrictive when increasing boost or tuning the engine. The do88 BigPack provides a direct-fit upgrade that delivers superior cooling capacity and airflow, ensuring consistent power output and improved reliability.

Unlike many front-mounted intercooler (FMIC) conversions that require modifications and may reduce efficiency, this BigPack fits perfectly in the stock position, offering top-tier performance with a simple bolt-on installation.
