 intercoolers- The function of the intercoolers is to reduce the intake air temperature. The turbochargers are extremely hot causing the air compressed to be thin from the heat. Increasing cooling efficiency makes cooler, denser, more combustible air. This means more power.

(SKU #IC100001)

 RS4 Intercooler set with silicone hoses. Increased horsepower, smoothness, and quality. Larger than Allroad coolers and all Aluminum construction.

 Bipass valves- Factory installed valves are a very weak link in the intake tract. Premium valves do not tear internally. This protects turbochargers from over rev and poor performance.
