I recently installed my AirMax CAI on my Merc. I have been enjoying the increased throttle response, driveablity and fuel mileage the last few weeks.
Even though it is a relatively simple job, I thought I'd take several pictures of the install process.
Step by step:
You should begin with something looking like this:
Loosen the hose clamps at the throttle body and MAF
Remove the hose that connects to the oil fill neck that is on the top of the intake tube
It is a barb type fitting, wiggle it back and forth to remove.
With the hose removed, the intake hose/tube can be removed. It make take some wiggling to get off the throttle body and MAF
The MAF is attached to the air box by 4 coarse thread bolts. A 10mm wrench is the size needed. I chose to remove the MAF from the air box in the truck- it can be done after the box is out.
To remove the air box, lift on the inside edge of the box straight up. Once it snaps up, wiggle it toward the inside, it should release from the fender
The box removed
Remove the back screw from the air box tray as I am pointing to with the screwdriver
Now that all factory air box components are removed, its time to assemble the AirMax intake.
The intake consists of 3 main parts-
The tube
The heat shield/filter adapter
The Filter- yes its an angled base filter
Start by attaching the factory MAF to the filter housing using the 4 bolts per the instructions. Put the included gasket on the heat shield, then line up the MAF. It has needs to be oriented correctly, if necessary take the heat shield, line the tab up with the hole left by the bolt you removed earlier to ensure the MAF is not upside down.
Now put the heat shield with the attached MAF under the hood, line the tab up with the hole, install the metric bolt included with the kit
Now take the tube, attach the couplers on both ends along with two clamps on each end. Tighten the two clamps that go on the tube itself as shown, leave the other two clamps loose, but on the couplers
Start by attaching the coupler to the throttle body
Then the MAF end.
Tighten the hose clamps on the TB and MAF
Attach the MAF connector to the MAF
Put the hose connected to the filler neck in the grommeted hole on the tube
Almost done-
Slip the filter on the heat shield-
Tighten the clamp on the filter
Double check all bolts, clamps and electrical connections
Completed.
I have seen an increase of 1 - 1.5 MPG consistently since I installed this CAI as well as a significant increase in throttle response.

Keep in mind, I have 33" meaty tires and an Aussie Locker. I rarely romp on the throttle or drive hard so this came as a surprise to me.
