Give your Audi S3 8V or S3 8.5V facelift the upgrade it deserves with this Stage 3 performance Kit. With this package, you’ll get the most power for your money and turn your S3 into a real performance beast. Instead of squeezing the absolute maximum out of the original IS38 turbo, you replace it straight away with the more powerful Endura IS38 performance turbo, designed for maximum flow, reliability and raw power at higher power outputs.
The kit tackles all the restrictions: Intake, exhaust, fuel system, cooling and ignition. The result? A significant power gain that you’ll feel with every acceleration, combined with an aggressive sound that’s perfectly suited to a Stage 3 S3.
What makes this kit unique is that it comes fully complete with 12 top-of-the-range upgrades. No separate purchases, no worrying about forgetting anything – everything you need for a complete Stage 3 build is included.
Please note: a professional ECU and TCU tune is mandatory. Without modified software, you won’t be making full use of the hardware and you run the risk of engine damage. Need help finding a tuner? Feel free to get in touch with us.
