1.

We will start by removing the stock airbox. Loosen and remove the rubber inlet
tube and disconnect the sensor plug.

3. Unclip the sensor wire from the secondary box.

2. The airbox can now be pulled out. Make sure the rubber mounting bushes are still on thecar – if not, remove from the airbox and install back onto the chassis.

4. Pull the spring clip away from the turbo tube flange and this will allow you to pull the tube
away from the turbo. Pull the tube off the turbo and then proceed to remove the breathers –see next steps.

7. Remove the tube completely. Make sure the rubber mounts are in place.

8. Remove the clip and the internal ring gasket from the OEM tube at the turbo side. Note theorientation of the gasket before removal - it needs to be in the same direction on the newflange.
