Welcome to the ultimate Boost Pipe Kit for the Audi RS3 8V.2 & 8Y and TTRS. The RacingLine Boost Pipe package replaces the original plastic charge pipes with a larger 70mm diameter aluminium boost pipe and beautiful smooth-flowing silicone replacement hoses, to help increase airflow under the demands of high heat and boost levels.
Direct OEM replacement: simply remove those weak, flexible rubber hoses and replace them with our five-piece kit
Pressure tested far beyond the turbo’s capabilities, the system maintains performance under extreme temperature and high-boost conditions
Stepped internal joint transitions give a port-matched laminar airflow path, greatly reducing turbulence versus non-stepped designs
70mm OD aluminium boost pipe – maintains intercooler diameter outlet all the way to the throttle body (Factory plastic boost pipe = 63mm OD)
Constructed from reinforced high quality silicone, guaranteeing great rigidity to prevent deformation under high boost or heat loads
