1.

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

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.

3. To remove the rubber intake tube – firstly pull out the spring clip around the tube at theturbo inlet end. The next photo shows a close up.

4. Pull the spring clip away from the tube flange and this will allow you to pull the tube awayfrom the turbo. There is also a breather connector to remove – see next step.

5. Remove the breather connector from the tube.

6. Remove the inlet tube completely from the engine.

7. Remove the temperature sensor from the airbox.

8. Take the machined flange and the silicon reducer – we will now prepare these for
installation onto the turbo inlet.

9.

Remove the rubber O-ring from inside the OEM tube and also the spring clip.

11. Install the spring clip as shown.

INTAKE SIDE

10. Insert the O-ring into the new flange as shown. The flat face of the O-ring should face theturbo side.

12. Now push the silicon onto the flange with the 2 hose clamps and only tighten the clamp
around the flange.

18. Install the temperature sensor onto the tube using the supplied screws. DO NOT use thestock screws.

.

19. Carefully lower the airbox into the engine bay. Note that the secondary scoop circled
above goes into the gap shown in the next photo. Also the mount circled blue should sit in
the rubber mount shown in next photo.

20. Gap in the wheel arch area and rubber mount.

21. The main opening of the airbox should sit inside the stock duct – next photo.

22. Ensure the opening sits squarely on the stock duct.

.

23. Lower the airbox with the tube angled downwards and ensure the mount and secondary
scoop go into place as described previously.

24. Bring it down at a slight angle with the front duct to locate the mounts and thesecondary scoop as above.
