Selection & installation tips

• Engine & platform: confirm EA888 Gen.3 and MQB layout (1.8 TSI / 2.0 TSI) before ordering.
• Current turbo ID: if your car is based on IS12/IS20/IS38, verify your current turbo code and connection layout for a clean match.
• Connection points: compare inlet, downpipe side, and hose/pipe interfaces to your existing setup before final assembly.
• Actuator wiring: verify the electronic actuator connector and keep the harness routed away from heat sources.
• Oil & coolant circuits: inspect lines, seals, and lubrication cleanliness during installation.

To ensure correct fit, always verify engine/platform match, connection points, and available space against the technical specs above and your vehicle’s current turbo and piping interfaces.
