Piping kit for MQB EA888 Generation 3 engines — TA Technix

Between the turbocharger, intercooler and engine, air flows through pipes. The original ones are often made of rubber: under pressure they expand, absorb some of the pressure and delay throttle response. At high pressure, they eventually come off, causing the car to go into limp mode at the worst possible time.

On the intake side, the original turbo inlet pipe is often narrowed for noise-reduction reasons. Enlarging it allows the compressor to breathe: a gain that is especially noticeable on an engine that has already been remapped.
