Stock Intake Removal

Start by unplugging your MAF sensor from the wiring harness by gently pushing down on the tab.
With the harness removed, gently pull the release tabs for the harness away from the tabs on the box to pop that plastic sheathing up and remove it from the airbox.
Gently pry outward on the sheathing to release the plastic cover from the wiring itself. We’ll come back to this in a later step. Set the hard plastic somewhere safe if you want to go back to stock in the future.
Keeping with the wiring theme, there are two harnesses going up to the battery clipped into opposite sides of the intake box. Squeeze the plastic tabs to remove those harnesses from the airbox. If you miss this step it may break the ears off of the airbox.
Go ahead and remove the two t-30 torx screws holding the 2 bolt flange onto the intake tube. a short extension can help you to get the back one.
Using your Phillips screwdriver or a 5.5mm socket, undo the hose clamp going to the aluminum pipe going over the turbo, and where it attaches to the airbox.
You should be able to wiggle the intake pipe off of the airbox and then off of the aluminum intake tube. After that, slowly work it off of the metal line that goes into a hose clamp. Unlike ours with the screwhead (which has been off previously) most of these have a worm clamp with a broken off head from the factory so that you won’t work on your own car. We found that you can slowly wiggle the tube free and then remove the clamp afterwards rather than trying to turn it or cut it off.

The clamp will usually look like these with broken off heads.
With the tube removed, take off the two 10mm bolts on the front edge of the intake scoop.
There are two 10mm bolts left holding the airbox in place. The first is down in the corner between the airbox and ecu.
The last piece to remove is the 10mm bolt back by the battery.
Once all 4 10mm bolts are removed you can pull gently upwards and wiggle the intake out of the engine bay.
The last step of disassembly is using a #2 phillips to remove the two screws holding in the MAF sensor. Pushing in towards the screw fairly hard helps to avoid stripping the screw. Set the MAF and screws in a safe spot, we’ll be using them in a little bit.

Pre-Installation

Using the two small allen bolts, install the bracket into the side of the airbox with a washer and nut on the back side.
Take the mounting bracket and install the larger bushing with the cobb logo then push the large-sized aluminum insert into it.
In the two holes on the leading edge of the airbox, install the two rubber grommets with rounded edges, then add the hollow spacers into each one (this prevents you from clamping down too hard on the carbon.)
Insert the MAF housing through the inside of the airbox and poke it out the back.
On the back side of the MAF housing, use the provided load spreader to line up with the three lower bolt holes (with the hole for the MAF sensor at the top) and screw in the three provided m6x12mm allen bolts to hold the housing into the airbox.
Slip the large hose clamp onto the airfilter then stick the airfilter into the airbox about 90 degrees off then rotate it over and onto the maf housing before tightening the clamp with a 8mm wrench.
Install the supplied gasket to the inside of the lid for the airbox.
You can pop the lid on now slipping the front tab into the slot and then using the rotating toggle to hold it in place.
Grab the MAF harness you removed the hard plastic shell from earlier. Slip the provided split loop over the harness, I usually start with the wire portion because it’s the thinnest, then once it’s all on, push it slightly over the rest of the split loom on either end to encompass more of the harness.
If you want, you can cover this portion with electrical tape, but water intrusion shouldn’t be a big concern for this portion of the harness.
Lay the harness across the area where the airbox was, tucking it up by the radiator hose.
Slip hose clamps over each end of the large silicone coupler and push it on to the maf housing.

Installation

Lay the intake place starting with the coupler going over the charge pipe above the turbo, you may need to twist it a little to get the airbox and fittings to all line up neatly with eachother. The two holes in the front edge of the scoop should line up with holes on the radiator support, and the rear bracket should line up with the bracket in front of the battery. You can loosely pop in the silver m6x30mm allen bolt in the rear hole to keep things somewhat lined up.
Using the provided m6x20 Allen bolts, go ahead and loosely bolt the airbox down in the front.
Install the two bolt fitting from the car side onto the matching two bolt fitting on the intake side, make sure to match up the inner raised portion of the fitting with the matching lowered portion so it actually tightens down on the o-ring. Pop it into the intake silicone and secure it with the #8 Clamp
Install the metal hard line into the silicone and tighten the hose clamp.
Install the MAF sensor with the arrow pointing towards the engine. Secure it with the stock hardware.
Route the MAF harness under the airbox thenclip it into the supplied wire clip on the side of the airbox before plugging it in to the MAF sensor.
Tighten down all the bolts and hose clamps.
You’re all done! Go out and enjoy!
