Our own Jackβs 325d E91 getting an intercooler upgrade.
Hereβs the original intercooler next to the new Airtec unit, and the difference speaks for itself. The factory intercooler is smaller, more restrictive, and far more prone to heat soak, especially once a diesel turbo car is driven hard or tuned. The Airtec replacement gives you a much larger core, improved airflow, and better cooling efficiency where it matters.
Benefits of the upgrade:
β’ Lower intake air temperatures
β’ Reduced heat soak under repeated load
β’ Improved airflow and charge air cooling
β’ More consistent performance
β’ Better support for tuned applications
The standard intercooler can quickly become a limitation on many turbocharged diesel and petrol cars. A larger upgrade like this helps keep charge temperatures under control, which means denser air and more consistent performance.
We also supply Airtec intercoolers for a wide range of applications, including BMW and VAG vehicles, so if you are planning upgrades for your own car, get in touch!
