Endura | Audi S3 8V / 8.5V-01
Give your Audi S3 8V or S3 8.5V facelift the upgrade it deserves with this Stage 3 Performance Kit . This package gives you the most power per pound and turns your S3 into a true performance monster. Instead of squeezing the stock IS38 turbo to its limits, you replace it directly with the more powerful Endura IS38 Performance Turbo , designed for maximum flow, reliability, and raw power at higher outputs.
The kit addresses all the restrictions: intake, exhaust, fuel system, cooling, and ignition. The result? Serious power gains you'll feel with every acceleration, combined with an aggressive sound perfectly suited to a Stage 3 S3.
What makes this kit unique is that it 's fully complete with 12 top upgrades . No separate purchases, no worrying about forgetting something – everything you need for a complete Stage 3 build is included.
Note: Professional ECU and TCU tuning is mandatory. Without custom software, you won't be able to fully utilize the hardware and risk engine damage. Need help finding a tuner? Feel free to contact us.
