K04 Turbo Discharge Pipe – Durable Aluminium EA113 Upgrade

K04 Turbo Discharge Pipe Kit — The K04 Deserves Better Than a Factory Plastic Pipe

You went K04. Smart move. Whether it came factory in your S3, TT-S or Golf R, or you swapped it yourself, you already know the K04 is a seriously capable turbo with headroom most people never fully explore. But here's the frustration — Audi and VW's factory discharge pipe is a weak link that doesn't belong anywhere near a tuned EA113 setup. Restrictive, heat-prone, and on borrowed time the moment boost levels climb beyond stock.

This K04 Turbo Discharge Pipe Kit is built from 6061/6063 aircraft-grade aluminium with a high-quality powder coat finish — the kind of materials that belong in a proper performance build, not a cost-cutting factory spec sheet. The improved bore and smooth internal flow path give your K04 the unrestricted discharge path it needs to move air efficiently, reducing intake temperatures and improving airflow measurably on the logs. The result on a mapped car? Between 10 and 15 hp of real, dyno-backed gains — and more importantly, a cooler, more consistent charge that makes your map work harder for longer.

This isn't just a power mod. It's reliability insurance. A proper aluminium discharge pipe eliminates the weak points that crack, deform and fail under sustained boost — so whether you're running a stage 1 map or pushing beyond, you're not gambling on a factory plastic pipe holding it all together.

Fits the entire EA113 K04 family — S3 8P, TT-S MK2, Golf R MK6, GTI ED30 MK5, GTI ED35 MK6, Scirocco R MK3, Seat Cupra R and more.
