PARTS INCLUDED: NM.658858 / NM.658858.1
TOOLS & SUPPLIES REQUIRED:
1. Disconnect valve cover breather hose from turbo intake pipe,
unclip wire connection then cut off hose clamp and remove
plastic fitting.
4. Remove T25 TORX screw located on passenger side of air
filter box and lift off. NOTE: There are [3] pin mounts that are
pushed into rubber grommet mounts on intake manifold, so
effort may be required to lift air filter box off of mounts.
5. Locate fresh air pipe that is attached to air filter box.
Disconnect fresh air pipe by rotating the connection counter
clockwise and pulling pipe away from air filter box. Remove
air filter box from vehicle.
2. Disconnect vent hose on side of turbo inlet pipe, unclip wire
connection then cut off hose clamp and remove plastic fitting.
6. Disconnect any wire harness and hose supports on intake
tube then loosen clamp at turbo and remove.
8. Install MAF sensor to NM stainless steel intake pipe bracket
using supplied M6 x 16mm button head bolts and M6 nuts.

9. Install NM SS bracket onto factory air filter box mounts.
NOTE: Make sure rubber grommets are still in place and not
attached to bottom of the OE air filter box. From bottom side
of mounts, install and tighten using supplied M8 washers and
M8 lock nuts. [13mm wrench]

10. Reconnect MAF sensor electrical connector.
15. Loosely install silicone turbo inlet hose onto turbo using
supplied #28 hose clamp. NOTE: Do not tighten at this time.
21. Locate previously disconnected heater wires from breather
hose and vent hose. The supplied resistor harness connects
to the front connector that attached to the valve cover
breather hose. The other supplied resistor harness connects
to the rear connector that attached to the vent hose on the
factory intake pipe.
11. 2011-3/2012 EARLY N18 Remove protective film from
double-sided tape on stainless steel fresh air hose bracket.
Slide bracket down between ECU and black plastic ECU
mount, while keeping double stick tape from touching. With
bracket pushed all the way down, press against ECU.
12. 2011-3/2012 Early N18 Attach brake booster line holder to
forward mounting hole in bracket. Secure fresh air pipe to
rearward mounting hole using supplied M6 x 10mm button
head bolt. [4mm hex key wrench]
13. 3/2012-UP N18 ECU cover removal: Remove 10mm hex bolt
then push inward on tabs to remove cover. Remove
protective film from double-sided tape on stainless steel
intake duct support bracket. Hook bracket on top edge of
black plastic case for ECU, positioning at back corner.
14. 3/2012-UP N18 Attach brake booster line holder to rearward
mounting hole in bracket. Secure fresh air pipe to forward
mounting hole using supplied M6 x 10mm button head bolt.

16. Connect breather hose with 25mm clamp supplied.
17. Install vent hose to “Y” breather adapter. NOTE: Spray inside
of hose with WD-40 or equivalent to ease installation.
18. Install and tighten silicone hose coupler onto MAF sensor
using supplied #44 hose clamp.
19. Loosely install supplied #44 clamps onto both silicone hose
ends, then install air intake pipe into silicone turbo inlet hose
first and then into MAF sensor hose. Adjust as necessary for
clearance, paying close attention to clearance of silicone
turbo inlet hose and coolant reservoir bottle. Tighten all
clamps. NOTE: Do not forget to tighten #28 hose clamp from
Step 14. Connect breather hose to cylinder head cover.
20. Using degreaser or contact cleaner and shop rag, clean inner
mounting flange of NM filter. Install NM filter onto MAF
sensor and tighten with long skinny screwdriver thru logo cutout or from back side of bracket.
