Finally give your Seat Leon 5F Cupra the muscle it deserves with this Stage 3 performance Kit. This package gives you the most power for your money! Ideal for anyone ready to make the leap to a serious turbo upgrade. Instead of squeezing every last bit of performance out of the original turbo, you’ll replace it straight away with the powerful Endura IS38 performance turbo, designed for maximum flow, reliability and raw power at higher power outputs.
This kit tackles all the restrictions: Intake, exhaust, fuel system, cooling and ignition. The result? Significant power gains, explosive acceleration and an aggressive sound that makes every journey a thrill.
What makes this kit special is that it comes complete with 12 top-tier upgrades. No separate purchases, no wondering if you’re missing anything: everything you need for a full Stage 3 build is included.
Please note: to get the most out of this kit, a professional ECU and TCU tune is essential. Without modified software, you won’t be making full use of the hardware and you run the risk of damage. Need help finding the right tuner? Feel free to contact us for no-obligation advice.
