AirMax Cold Air Intake Installation 2nd Gen 5.0

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:

AirMax_003_Medium_.jpg


AirMax_005_Medium_.jpg


AirMax_002_Medium_.jpg


Loosen the hose clamps at the throttle body and MAF

AirMaxII_020_Medium_.jpg


AirMaxII_021_Medium_.jpg


Remove the hose that connects to the oil fill neck that is on the top of the intake tube

AirMaxII_035_Medium_.jpg


It is a barb type fitting, wiggle it back and forth to remove.

AirMaxII_036_Medium_.jpg


With the hose removed, the intake hose/tube can be removed. It make take some wiggling to get off the throttle body and MAF

AirMaxII_037_Medium_.jpg


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.

AirMaxII_039_Medium_.jpg


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

AirMaxII_040_Medium_.jpg


The box removed

AirMaxII_041_Medium_.jpg


Remove the back screw from the air box tray as I am pointing to with the screwdriver

AirMaxII_042_Medium_.jpg


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

AirMaxII_074_Medium_.jpg


The heat shield/filter adapter

AirMaxII_045_Medium_.jpg


The Filter- yes its an angled base filter

AirMaxII_047_Medium_.jpg


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.

AirMaxII_046_Medium_.jpg


AirMaxII_069_Medium_.jpg


AirMaxII_070_Medium_.jpg


AirMaxII_071_Medium_.jpg


AirMaxII_072_Medium_.jpg


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

AirMaxII_073_Medium_.jpg


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

AirMaxII_074_Medium_.jpg


Start by attaching the coupler to the throttle body

AirMaxII_075_Medium_.jpg


Then the MAF end.

Tighten the hose clamps on the TB and MAF

Attach the MAF connector to the MAF

AirMaxII_076_Medium_.jpg


Put the hose connected to the filler neck in the grommeted hole on the tube

AirMaxII_077_Medium_.jpg


Almost done-

Slip the filter on the heat shield-

AirMaxII_078_Medium_.jpg


Tighten the clamp on the filter

AirMaxII_078_Medium_.jpg


Double check all bolts, clamps and electrical connections

Completed.

AirMaxII_081_Medium_.jpg

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.

I give it :thumbsup::thumbsup:

What are dimensions of the pipe? Looks like (4"dia.)x(10-12"length)x(4-6"leg). It really shouldnt be that hard to find parts to make the exact same thing without paint and heatshield for $50 or so.

Evan-
Why do they call it "spiral flow"?

Does it have unique sound characteristics?

That tube running from your filler neck to the air tube looks awful familiar :p:

I don't think so- I did at one point though. I bought a filter, MAF to filter adapter, had couplers and mandrel bent aluminum tubing given to me and still it cost me more than $50. And, because of some unknown issue, my MPG's and power went down. The people that make those intakes know what they are doing, they have the money to properly research and design a product that works well.

They call it "spiral flow" because some models have an insert with spirals. I suppose it could help swirl air :dunno: Unfortunately, this model does not have this insert for some reason.

Finally.. I was waiting for this... nice review/guide.

The spiral flow is supposed to refer to a tornado like device in the tube, I find it odd his didn't come with it.

MountaineerGreen, would you say you got a bigger increase in performance/mpg than the Mac? Would you say the increase in price is worth it? Performance wise..

I've never run a MAC, so I can't testify to the difference. I don't know what the MAC costs, but IMO the addition of the heat held and the use of steel vs. aluminum would be worth the extra $$.

It's around $169 or so, I wish the AirMax came in a different color.. but that's just me being picky.. Didn't aldive figure the iat doesn't affect hp as much as people usually say?

At first, I was hesitant because of the color, but once its in there, it looks really good, the powder coat finish really looks nice. If you are concerned, buy the CAI, ship it to jtsmith, he can coat it whatever color you desire, then ship it to you.

Haha, more money than I can afford right now. Would be interesting what jtsmith would do though.

I bought all of my intake tubing from intakehoses.com a K&N filter and a Lightning MAF adapter and it cost me about $200.
