1.

We will start by removing the stock airbox system

3. Remove the hose from the clips around the rear of the airbox.

2. Remove the MAF sensor plug located at the back of the airbox.

4. Loosen the hose clamp which secures the inlet pipe to the back of the airbox.

Installation Instructions : BMW N20 : Page 2

5. The Airbox can now be removed by lifting it out of the rubber mounts and inlet tube.

7. Remove the inlet hose from the engine bay.

6. Loosen the lower hose clamp holding the inlet tube in place. Also remove the rubber hose
attached to the bottom of this tube – it is held in place with a clip and can be pulled off.

8. Pull the MAF sensor wire out of the clip located above the alternator. We will re-route thiswire.

9. Route the MAF sensor wire around the back of the coolant module as shown.

10. Take the 2 supplied cable clips for the next step.

11. Insert the clips into the 2 holes shown above – located above the fan.

12. Push the clips in fully with the openings facing the engine as shown.

Installation Instructions : BMW N20: Page 4

13. Route the hose removed from the airbox in step 3 over the fan and into the installed
clips as shown.

14. Remove the MAF sensor from the airbox – it is held in place with 2 torx screws.

Upper Housing Bracket
Lower DuctBracket

15. Install the sensor into the carbon tube – it must be installed in the correct orientation asshown. Secure with the 2 supplied Torx screws – NOT with the OEM screws.

16. Now take the filter housing assembly which also has the duct attached. The duct has alower mounting bracket which will secure to the chassis. The housing has an upper bracket
which mounts to the stock airbox mount.

Plastic Ridge
17. Lower the assembly into position and push the upper bracket mount into the OEM rubber
mount used for the airbox as shown. The rubber mount might still be attached to the airbox.

18. The OEM plastic duct should go into the carbon duct – there is a ridge on the plastic duct
which needs to also go inside the carbon duct, past the rubber edging.

.

19. The carbon duct should sit as shown – squarely over the plastic OEM duct.
.

20. Here is another angle showing the plastic duct fully inside the carbon duct. There is also abracket on the carbon duct which should line up with the 2 holes on the chassis as shown.

21. Use the supplied M6 Bolts and Lock nuts to secure the lower duct bracket to the chassis
as shown.

22. Push the supplied silicon coupler onto the filter housing with the 2 supplied hose clamps.
Leave half the silicon extending outside the housing for the carbon tube. Secure the clamparound the Housing.

23. Take the carbon tube and lower it into place.

24. Push the top of the tube fully into the silicon coupler. Do not secure yet.

25. Push the lower part of the tube into the inlet – notice that the notch on the tube shouldline up with the notch in the inlet hose.

26. Push the carbon tube fully into the inlet hose – the notch on the carbon should go into thenotch in the inlet hose. Secure the clamp around the hose.

.

27. Push the upper part of the tube into the silicon fully and secure the hose clamp.

28. Firmly push the MAF sensor plug back into the sensor.

29. Remove the left grill = it is held in place with 8 tabs which need to be pulled towards thecentre of the grill while pulling the grill out to release.

30. The tabs can be seen at the back of the grill.

.

31. Remove the protective mesh inside the opening behind the grill. This is done by pulling
the rubber tab and then taking the mesh out.

32. Insert the scoop into the nose of the bumper as shown and then rotate as shown in the nextstep.

Installation Instructions : BMW N20: Page 9

33. With the scoop rotated – now place the clip on the back of the scoop over the strut bar.

34. The clip should go over the strut bar.

.

35. Now push the scoop so that the clip locks over the strut bar.

36. Move the scoop down so that the end of the scoop goes into the duct opening.

Installation Instructions : BMW N20: Page 10

37. The end of the scoop should go inside the rubber duct opening.

38. The lower panel of the scoop should line up behind the grill opening of the bumper.

.

You have now completed the installation of the Eventuri N20 Intake System.
Eventuri cannot take responsibility for an incorrectly installed intake or any
damage caused during installation.

39. Push the grill back into place.
