10. Remove the MAF from the stock air box. There are two very small phillips screws. You will not be reusing the screws.
11. Unpack the new Intake Tube. Make sure the two brass hex standoffs are securely tightened down by using a wrench on them. Temporarily remove the two small allen head bolts that are threaded into the brass standoffs.
12. Install the MAF into the Intake Tube. Note orientation of the MAF. It will obviously fit one way. Using the two allen head bolts and an Allen wrench, tighten the MAF so that it sits flush on the Intake Tube. Set the Intake Tube aside.
(here things get a little interesting)
13. Unpack the heat shields. There are two black sheetmetal parts that are connected with two DZUS fasteners. If these are together, separate them now.
14. From the wheel well side, roughly fit the small heat sheild into position. It will sort of wedge in there. The two DZUS fasteners will be towards the top. The shield's bend will be towards you and the shield will sit at an angle with the two rounded openings or reliefs on the sides going around the tubes and harness bundles.
15. Remove the two bolts holding on the engine coolant reservoir. One bolt is accessed from the engine bay side easily using a 10mm wrench. The other is accessed from the wheel well side. Unbolt that one from the top using an 8mm (I think) wrench. Carefully set aside these two bolts. From the engine bay side, pull the coolant reservoir away from its mounting points. Leave all tubes attached. You will only need to just pull the reservoir aside a short distance.
16. Now place the upper shield in the engine compartment (working from engine bay side). This will take a bit of angling in to get it in. Roughly place it where it will end up. The mounting tab will be near the 13mm bolt mounting hole for the stock air box. I recommend lining up this hole and then starting to thread in the 13mm bolt. Do not fully install this bolt yet.
17. Now line up the DZUS fasteners on both the upper and lower shields. This is tricky to do and to also have access to the turning side of the fasteners. I found I could turn them with either my fingers or the edge of a dime. It may take a second person to hold things or to have three hands. My solution which worked a treat, was to use a small clamp to hold things in alignment, and then I would go to the engine bay side and tighten the fasteners (one at a time).
ForcedFed's instructions take note that you may have to reroute some coolant or wiring harness bundles, but I found I did not have to do any of that.
