What do they do?

Welcome to the RacingLine Hard Boost Pipes for 2.0TSI EA888 gen.4 MQB ‘Evo’ vehicles.
By promoting increased airflow through a smooth and uninterrupted charge path, along with removing boost-leak weak points, performance and reliability gains are guaranteed.
By minimising restrictions, the smoother airflow and optimised routing ensures the turbo meets less resistance and can thus perform more effectively – moving a larger volume of air and minimising turbulence.
As well as giving increased turbocharger sound and faster spool, performance gains are guaranteed through upgrading each of the factory components between the turbocharger, intercooler, and throttle body.
The Boost Pipes themselves are formed from a single piece, mandrel-bent 6000 series aluminium tube with thin wall 60mm OD for maximum smooth air flow.
Direct OEM-replacement for easy install. The Boost Pipes can be used with either factory rubber hoses or, for best results we’d highly recommend that you pair them with the gen.4 RacingLine Boost Hose Kit (VWR140006)
