| 1 - | Air flow hoses and pipes between the turbocharger and the intercooler |
| 2 - | Air flow hoses and pipes between the intercooler and the intake manifold |
| 4 - | Joint under the supercharger pressure sensor -G31- |
| 5 - | Joint between the intake connection sleeve, exhaust gas recirculation valve and the intake manifold |
| 6 - | Gasket between intake manifold and cylinder head |
