Etuners intercooler for EA888 Gen3: +78% volume and stable power

Intercooler Etuners Parts for EA888 Gen3 (MQB)

The intercooler Etuners Parts is specifically designed for EA888 Gen3 (MQB) engines and is intended for operation under increased thermal loads — from Stage 2 to configurations with increased boost and prolonged load.

The design is based on a Bar-and-Plate type intercooler core with offset internal fins. This geometry significantly increases the heat exchange area and creates controlled turbulence in the airflow, allowing for effective reduction of intake air temperature without critical pressure loss.

The increased thickness and volume of the core provide high thermal inertia and stable operation even under multiple accelerations and prolonged loads. Compared to the stock intercooler of the Golf R, the core volume is increased by 78%, which directly reflects on power stability and repeatability of results.

The intercooler is made of aluminum and fully welded using the TIG method, ensuring high strength, tightness, and resistance to increased pressure. The design maintains the exact geometry of the stock unit and does not require modifications during installation — it is a complete bolt-on solution for everyday use and motorsport.
