The CTS Turbo FMIC for the Audi A4 B6 is rated for up to 600 hp and reduces charge-air temperatures, improving engine performance. For effective charge-air temperature control, it uses a high-density intercooler with a core measuring 20″ × 11.25″ × 3″, manufactured in a bar-and-plate design.
The CTS B6 A4 FMIC kit enables maximum airflow through the intercooler and reduces the risk of heat saturation. The original intercooler can heat-soak very quickly when running increased boost pressure above the standard level.
Available for the standard K03/K04 turbo or upgraded turbo kits such as the K04-015, as well as Eliminator kits.
Weight: 13.61 kg
Suitable for: Audi A4 II (B6/B7).
