CTS Turbo now offers a full silicone intercooler hose set for the B7 Audi A4 2.0T FSI. The hoses that come stock with your A4 age and deteriorate over time. This will lead to inevitable boost leaks leading to loss of power and increased wear on the turbo. CTS Turbos hoses are far more durable and are guaranteed to not crack. Our super rigid construction eliminates hose expansion and deformation under high boost pressure.
