This should be good, I've been wondering about this for a while!! Finally a diffinitive answer on whose intake flows more air....waiting patiently.

 

Well??

 

Where-ya at Jr.?

 

I am also very interested to see the results. Doug don't keep us in suspense....wondering what difference the tunes will be from the C&L.
interesting........

 

Yeah you're right, my goof. Been a while since I looked at it.

I believe my JLT I without the reinforcement insert is 88.9mm (3.5")...most seem to refer to it as a "90".

Looking forward to it!!

 

Just put on the GMS CAI w/MAF and the car started right up. The only thing was that I had an alarm, "Tire Pressure Monitor Fault". This came on everytime I started the car, but I checked the tires and all seemed fine. I took it around the block and the alarm went away and hasn't come back yet. Is this normal?? Has anyone else had this problem? Just curious. I love the sound and the extra zip the car has now. Now I have to think about the next mod.....hmmmm.

Did you unhook the battery when you did the install? The TPMS reset's itself if the power is cut, and just like when a tire get's replaced/repaired, it goes away after 2 minutes of driving. I've done both already, and the first time (tire relacement) it freaked me out, but about the time I got the manual out to check on it (before going back to the tire place) the light was out. Second time was when I put my GMS on, but by that time I was aware of the situation.

So the short answer is - it's normal.

 

Thanks and yeah I unhook the battery as directed. I am glad. I do love the CAI and I appreciate your help.

I did not experience anything like that... I did not disconnect the battery. I'm glad that it worked out for you though.

 

Houston, we have a problem. Got the CAI and installed it exactly per directions, and started up the car and noticed right away that the engine idled fast around 1k-1.1k RPM. Figured it was cold and the RPMs would come down. Then I start taking it down the parking lot and right around 20 mph....BAM! The car shuddered as limp-home mode was activated and the wrench lit up on my dash. So I stopped the car and restarted it and the wrench went away only to activate the next time i hit about 20. I kept driving anyway to see if it would go out but soon afterward the check engine light came on. I unplugged the negative battery cable before the install and tried yanking the power again after the check engine light came on with no change. The wrench still lights up at about 15-20 MPH, or about 40 seconds of driving. Any ideas what's going on? Defective MAF?

 

Hummm, MAybe they sent you an 07 MAF instead of 05-06 MAF. There is a difference... Not sure what the problem is.... Contact GMS, they'll remedy the problem regardless.

 

Check to make sure you put in the replacement MAF the right way inside the intake tube, with the airflow arrow pointing towards the throttle-body. Also did you put in the jumper harness.

 

Thanks for the quick feedback. The MAF was pre-installed in the intake tube, installed in the right direction. The numbers on it are AFH60M-19, 6H05, and H38D. I also did use the jumper harness. One other thing that I'm wondering about is that the CAI came with 2 rubber hoses. A larger diameter one obviously for the breather hose, but then a much smaller one, maybe 1/4 inch or so. Anyone know what it's for? My only guess is an '07 thing or possibly for lining the inside of the cut out in the heatshield to prevent rattles. I reinstalled the stock intake for the time being and it runs fine, like nothing ever changed, check engine light went away and everything. Then i tried reinstalling the CAI but the same thing happened again.

 

I just installed mine not too long ago and I do not remember two hoses coming with the CAI. There was a breather hose, but that was all. I also unhooked the negative battery and the only alarm I had was a tire pressure alarm that cleared as soon as I drive it. The only problem I had was that the new metal box and the filter was a tight fit and I had to leave everything loose before I tighten it up. I would check the jumper to make sure the connections are tight. Just a thought.

 

Two hoses... Should've only been the breather hose. Are you sure that it's not the heat shield hood sealer, for a lack of a better term... ? It wraps around the top of the heat shield. Send pics... Nonetheless, "that" wouldn't have caused the problem. Give Jr. a call... Maybe you can track him down, he has been MIA from this form for a while.

 

JR was here at SEMA all last week (saw him a couple times) but should be back now. Anyone there should be able to double check to see if you got the right MAF though.

Mine went on without a problem, hope you can get yours resolved soon.

 

I think the small 1/4 " hose you are talking about is split to go on the front edge of the air box. Mine worked fine but I did have a little trouble getting the jumper wire to connect. Did you check the hose connection at the throttle body for a good seal?

 

I would give them a call, it may be that you've gotten a bad harness, it isn't unheard of.

 

I'm thinking the smaller hose may be for the heat shield, but it isn't split and the wrong length. JR's apparently back, so hopefully i'll get some help with these problems.

I definitely checked all the seals. One of the hose clamps barely fit (the one over the intake tube), but did finally tighten down good and makes a solid seal. Also checked the filter and the breather hose.

Here are the pics:

It is hard to tell by the picture. But the hole in the heat shield should have a rubber seal on it.If it doesn't then I would assume that the hose should be split and added to the hole on the heat shield. This stops the heat shield from cutting into the filter housing. The heat shield that I recieved had the rubber seal already on the shield. I did not have to install it.
