RS3 Boost Hose Kit

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

Fits:

2.5TFSI Engines (Code: DAZA, DAZC, DNWA, DXHA)

RS3 8V.2 (2017-2020)

TTRS 8S (2017+)
