1.

Remove the engine cover. Remove the 2 screws holding the inlet duct in place.
Then push the duct into the airbox to release the mounting points and remove ductfrom engine bay.

3a. Remove spring clamp from flexi hose at the turbo
pipe connection – use an appropriate spring clamp tool.
Pull out the flexi hose from the turbo tube. Also remove
engine cover and breather hose from the airbox.

2. Remove the breather pot from the airbox – it is held in place with a panel clip – use a small
flat head screwdriver to prise the clip open if required.

3b. For 2019+ DWNA engines the breather hose is attached
onto an adapter with 2 cap head screws. Remove thesescrews and remove the hose attachment to the airbox.

4. Remove entire airbox by pulling upwards. It is held in placewith rubber push mounts. Also remove the Airbox mounting tray
by unscrewing the 2 bolts.

ATTENTION
Hole should be blanked inside

If you have a 2019+ vehicle you might have this type of breather
from the throttle body to the airbox which was removed in step 3b.
If so please see next step.

With the breather hose removed you will be able to see this tube connected to the OEM airbox. Please
have a look at the square hole as indicated above. This should be blanked off on the inside. So you
SHOULD NOT be able to see all the way through this square hole. If you can see all the way though thishole and into the tube please DO NOT install the intake – contact your Eventuri Dealer.

Installation Instructions : STAGE 3 RS3/TTRS : Page 25. If you have a 2019+ vehicle with the above breather type please follow the next steps. If you
have the breather system from step 3a please go to step 9. Remove the breather hose fromthe throttle body by removing these 2 screws.

7. Install the seals into the new machined adapter fitting provided.

6. Remove the 2 rubber seals from the adapter fitting.

12. We now need to relocate this wiring harness located behind the engine.

Installation Instructions : STAGE 3 RS3/TTRS: Page 4

13. Remove the harness bracket from the chassis by using a small flat head screwdriver andcarefully lever it off – one side is pushed onto a threaded stud and the other side has a plastic
clip pushed into a hole on the chassis.

14. We need a bit more slack in the wiring – carefully pull the wiring through the cable ties toallow the plugs to move to the right. You only need a few centimetres extra.

15. Slide the both plugs out of the bracket as shown. Also remove the wire attached to thebottom of the bracket. We will not use the plastic bracket.

16. Remove the plastic bracket completely.

Installation Instructions : STAGE 3 RS3/TTRS: Page 5

17. Install the new bracket onto the threaded stud as shown and secure with the supplied
M6 Nut.

18. Place the wiring plugs into the bracket and secure with a cable tie. Cut the excess off.

.

19. Remove the breather tube from the yellow breather module. We also need to rotate aclip around the blue circled hose – see next step for details.
.

20. Rotate this clip so that the protruding leg is down the side. Otherwise it can scratch thecarbon duct.

21. Take the 2 supplied silicon tubes – they will be used to cover the coolant pipes shown inthe previous photo. These hoses have a slit down one side so they can be opened up.

22. Push Hose 1 onto the tube which we rotated the clip on as shown.

23. Push Hose 2 onto the pipe next to the previous one. See next photo for another angle.

24. The hose will stick up slightly – it is not meant to be completely flush with the metal tube.

25. Take the heat shield, tube bracket with rubber edge and the 2 supplied M6 Screws with 1
M6 Non Locking Nut.

26. The shield and tub bracket are mounted together to the same location at the back of theengine where the OEM tube was fixed (Step 5). If there is a cable attached by a clip to thisbracket – remove also.

.

27. Lower the shield at the back of the engine as shown. (Optional Carbon turbo inlet shown).

28. Position the Tube bracket behind the mount of the shield as shown and use the 2 M6screws to secure them. One hole has a captive nut, the other one requires the M6 nut. Position
the shield so it doesn’t touch the manifold shroud and secure the screws.

37. Take the carbon tube and place the straight silicon coupler over it with 2 hose clamps.
.

39. Tighten the hose clamp around the carbon tube only. Do not use a ratchet to tighten it – itjust needs to be finger tight. Over tightening can damage the tube.
.

38. Push the silicon onto the tube to leave about 30mm length remaining equally all the way
around.

40. Push the carbon tube into the silicon reducer as shown – don’t tighten the clamps yet.

41. Push the filter housing into the silicon coupler on the tube as shown. Eventuri plaqueshould be facing upwards and the bracket should rest on the previously mounted bracket.

42. The bracket on the filter housing should be flat against the previously mounted bracket. Do
not align then yet. Push the housing back as far as possible. We need clearance for the duct.

.

43. Before placing the duct – we need to cover this plastic tab with a cloth to prevent
scratches.

44. Put a cloth over that tab.

Installation Instructions : STAGE 3 RS3/TTRS: Page 12

45. Carefully angle the duct down as shown. The rubber seal will touch the filter housing andthe back edge should go inside the slam panel as circled. See next photo for another angle.

46. Another angle of the duct angled into place – notice the rear edge is inside the slam panel.

.

47. Now rotate the duct so the rear corner goes into the mounting location circled.

48. Push the engine hose forwards slightly to give the duct clearance to drop into position.

Installation Instructions : STAGE 3 RS3/TTRS: Page 13

49. Before securing identify the correct holes to use on the duct. The upper threaded inserts ascircled are to be used for the 8Y RS3.

50. – line up the hole on the panel with the correct hole on the duct as shown in previous step.
For RS3 Secure with a supplied M5 Screw. For TTRS secure with the original stock screws.

.

51. Do the same on the other side.

52. Take the 2 supplied M6 screws and Nylock Nuts

Installation Instructions : STAGE 3 RS3/TTRS: Page 14

53. Align the holes on the filter bracket with the slots on the engine bracket and push the 2screws though – it may be easier to push the screws upwards from underneath so that theaccess is easier for the nuts.

54. Line up the filter housing with the duct and then use the Nylock Nuts to secure the 2 screws
on the bracket.

.

2019 / DWNA
STEP 3b55. Pull the carbon tube into the filter housing, rotate if required for clearance over the brakefluid reservoir and secure the remaining hose clamps. Do not use a ratchet to tighten it – it justneeds to be finger tight. Over tightening can damage the tube.
