AFE Intake Installation Instructions
 


Congrats!  If you made it here, you successfully removed the stock airbox & intake and are ready to put in your aFe.

 

Tools you'll need:
    4mm allen wrench
    1/4" socket, nut-driver
    10mm socket or wrench
    Med flat screwdriver
    Torx bit T-20 (provided)

Step 1: Let's re-inventory all that came in your box.

You should have the filter (blue). A cleaning kit (the box). The aluminum shield (on left) the black housing, the billet adapter (round aluminum thing on the black housing) and a bag of bolts that includes one Torx bit T-20 (used later).  In the photo above I had already assembled the billet Adapter to the black housing.  Your billet adapter came in a separate box but assembles with four M6 x 1 x 10 mm bolts.

The first bit of assembly I did was install the billet adapter into the housing.  This next picture shows the back side of the housing with the billet adapter installed.

Step 2: Installing the housing into the engine bay

Remember that rubber mount you removed earlier?  Do you see the screws sticking up from where that rubber mount was?  One of those screws will slip through the slots on the bottom of the aFe housing.  It's easy to figure out which screw once you start working the housing in.  Go ahead and start working the housing into the engine compartment.  Guide the screw through the bottom of the housing until it rests on the bottom.

NOTICE - HERE IS WHERE WE DEVIATE FROM MANUFACTURER

Now here is where I and aFE disagree on what should be done next.  According to their instructions, you should secure the bottom of the housing with the washer and nut as you see in the picture below.  They suggest you do this BEFORE you try to get the billet adapter into the intake duct.  It was impossible for me.  I was ready to rip the entire thing out and throw it away at one point.  I remove the screw and washer you see below so that I had some 'play' while I worked the billet adapter into the intake track.  Do what you want but I thought it was worth sharing my experience.



Step 3: Connecting (inserting) billet adapter into Intake track

This was the least fun of the afternoon.  Remember that o-ring we mentioned earlier?  Well I found it was IMPOSSIBLE to install the billet adapter with that ring already in place.  I took it out of the duct and put it on the billet adapter.  Then I soaped that baby up a bit so I could get it to fit.  I bloodied 2 knuckles doing trying to get them to fit BEFORE I thought to soap it up.  Don't make my mistake :)
 



So above you can see I removed the ring, in the next picture you can see it on the billet adapter,  all nice and soapy.



Step 4: Loosening Intake Duct from Plenum

Notice also above that the aFe housing is at an angle.  This is why I 'unseated' it from the screw at the bottom.  I need the entire thing loose so I could work the billet adapter into the duct.  Once you get them connected, tighten the hose clamp as best you can.  Now, once these are connected, you probably noticed that the entire 'assembly' doesn't rest on the engine bay.  It is sort of 'hovering'.  If you try to force it down (don't do it), the billet adapter will 'pop out' of the intake.  This can be VERY FRUSTRATING because it likely took you 10 minutes or so to get it to go in.  The reason it doesn't rest is that you have to rotate the entire intake track where it connects to the intake plenum.  To do this, loosen the screw shown in the picture below.




Now grab the intake where it connects to the plenum and rotate the whole thing counter-clockwise until you see that the aFe housing is resting on the bottom and can now be secured with the washer and nut supplied.

Now re-tighten the hose clamp around the intake and plenum and re-secure the clamp around the intake and the billet adapter. 

Step 5: Re-securing headlight controller and side mount of housing

The two bolts you removed from the headlight controller need to go back in.  Bolt #1 goes back in with the aFe shield secured by the bolt.  Bolt #2 as you probably noticed doesn't do the trick anymore.  When we removed the stock airbox, we took out 1/2" of plastic.  Don't worry, aFe thinks of everything and has already supplied you with a nylon spacer.  As you can see below, the spacer has been installed and bolt #2 is in place.



Once the two bolts are in, put the black plastic cover back over the headlight controller and also reattach the headlight to the controller.  When all is complete, your engine bay should look like this.

Step 6: Installing the MAF into the billet adapter

Now it's time to remove the MAF from the airbox cover you removed earlier.  To do this, you'll need the Torx bit T-20 provided in the ziplock bag of parts from aFe.



Remove the two screws and gently remove the MAF.  Notice the green o-ring.  This provides a very tight seal so you may have to pull a bit to get the MAF out.  Once you have it out, insert into the top of the billet adapter as shown below.



Notice that due to the hole alignment, there is only one way to put this in so don't worry about getting it 'backwards'.  Now secure this with the two of the M4 machine screws provided.

Next, re-connect the MAF wiring harness.  It should all look similar to this.

Step 7: Installing the aFe filter

Now, open the box with your filter.  Smell it, it smells good :)  I love the smell of new car parts (ok, enough about me).  Loosen the clamp on the filter ALL THE WAY before you try to slip it over the billet adapter.  Also, when you are putting it on the adapter, DO NOT GRAB THE FILTER BY THE SIDES - you will crush the mesh.  Holt it from the back only and work it over the billet adapter.  Once installed, tighten the clamp with the screwdriver.  If you did it right, it should look like this.



Step 8: Installing the aluminum cover

This was a bit tricky.  I found that putting each of the screws in a few turns first and then tightening them down worked.  The toughest was the front right one, it connects to a free 'arm' of the housing and was a bit difficult to line up.  Keeping them all loose until you have them started is key to the success.  Once you have all screws started, tighten them down with the 4 mm allen wrench and your completed installation should look like this.

Step 9: Smile

After a few hours of driving, re-check all clamps, hoses and hardware and tighten if necessary.
