The factory IS38 turbocharger on the Audi S3 8V is highly capable, delivering excellent power straight out of the box. However, as you push for higher boost pressures with a Stage 1 or Stage 2 remap, the factory supporting hardware quickly becomes a weak point. Upgrading your turbo accessories is essential to ensure your engine holds boost reliably, manages extreme temperatures, and allows you to monitor vital performance data in real-time.

Turbo Dump Valves: The factory plastic diverter valve is highly prone to leaking under increased boost. Swapping to an uprated piston-style turbo dump valves setup ensures your engine holds maximum pressure safely, while offering sharper throttle response and the option for a vent-to-atmosphere (VTA) sound.

Turbo Blankets: Pushing higher boost generates massive radiant heat. Installing premium turbo blankets isolates the hot side of your turbocharger, drastically reducing engine bay temperatures, preventing heat soak, and improving spool times.

Gauges & Hardware: Keep a close eye on your engine's performance with highly accurate boost gauges, and browse our misc turbo parts for the essential lines, fittings, and accessories needed for a flawless installation.
