Porsche, intake manifold replacement in Israel.
You need to replace the intake manifold if you notice the following signs: unstable speed, rough engine performance, increased fuel consumption, low thrust and loss of power. The procedure for replacing the intake manifold on different car models can be different and can include such operations as removing the fuel pump fuse, turning the battery off, removing the air filter tubes and the filter itself, removing the inlet pipe assembly and the manifold itself.
