Seat Leon 1.8 TSI Gen3 – Stage 3 IS38 turbo (Golf 7R turbo) 98RON

Nothing beats a 1.8TSI engine with the performance of a Golf 7R. This is why we use the turbocharger unit, IS38, from the Golf MK7 R 2.0 TSI. It is a direct bolt-on replacement to the stock unit in the Leon. This upgrade applies to manual gearbox models. The DSG7/DQ200 gearbox versions require torque limitations in order for the upgrade to work so as to avoid destroying the transmission.
