Are you running a larger compressor wheel? Strengthening the silicone is easy enough, it's the MAF being so close to the filter is what is worrying me. The stock airbox is going back on for the winter anyway so I have t he winter to figure something out. I going to try running a filter with a "funnel" on the end like the S&B and Fujita filters and see if the "swirling" will help with the turbulence at the MAF.

 

what happens when this collapsing happens? im not sure if ive ever experienced it

 

nope stock compressor.

 

It chokes off the air to the turbo and that is very bad. Think about it this way.........go take a **** break and once you start the "flow", grab the tip of your pecker as hard as you can! Once you choke off the flow bad things will happen lol.

 

Depending on how much of the tube is collapsing this should work. We had a few tractors on our construction sites in the past that have had some collapsed hoses(cooling and turbo) and they where special order parts, so in while waiting for the new and improved parts to come in we would simply take a warm drive clamp and tighten it around the area and that kept it from collapsing. Ideally this intake piece should have a metal coil sandwiched between a thicker inner layer and a thin outer layer for aesthetics.

Wish I could be of more assistance but I don't have an intake and I am holding out until all of these issues are resolved.

 

ROTFLMMFAO. Good analogy.

 

I had a feeling you would like that one

 

Well the stock, modified airbox went back in today. I took it for a short drive and the BPV flutter is gone. Now here is where it gets interesting.........I put the AEM tube and filter on a buddies' stock elbow from the turbo and his car drives fine also. His car does not exhibit any flutter or driveability issues so far. I'm going on a little drive tonight so we'll see for sure how the car drives but it feels like it does pull harder, the tq feels more "robust".

*EDIT*

Modified airbox is in with the AEM silicone elbow and the BPV flutter is still there as well as the low rpm on/off throttle surge but MUCH better than the full AEM system and the car pulls harder too. I need to do a bit of tuning and we'll see what the verdict is.

eman777, can you explain a little what your problems are?

 

Same results I got. I might be installing it back on my car with the stock intake tube I just wish the stock tube was a tad larger overall.

 

When you fit the stock elbow to the AEM tube, the stock elbow is just a wee bit short. You can force the elbow forward a bit but it will put stress on the PCV fitting, you'll see what I mean when you test fit it.

 

Unclamping and rotating the elbow on the turbo might help some. I did notice that the AEM elbow is a tad longer overall then the stock one.

 

So essentially this choke can cause the engine to shut down? or does it just put a lot of stress on the turbo? also, on a scale of 1 to 10 how dangerous for my car is it to leave my aem intake on it?

 

I have the cold start whoosh sound. And sometimes i feel like my car is not getting enough air. like it doesnt pull as hard as it should. I dont know i just do not want the thing to totally collapse.

I have a question, what goes into the stock airbox mod?

 

Somehow I overlooked this thread until now. Installed the AEM elbow last week and noticed a couple of the issues mentioned here. I'm back to the stock filter and haven't modified the snorkle either which I'm guessing may contribute to the suction/partial collapse. I'm not too keen on the brittle plastic breather fitting on the stock piece but it's probably going back on for now.

you gotta remember... they make the intake and do it within two to 3 days... i can see why you guys would have problems... also, if the person volunteering the car doesnt really tell them. oh hey theres a problem, they arent going to know. Now that you guys are saying, hey theres a problem, AEM is responding... i dont know if you guys know but they are looking for another Cobalt SS again... trying to fix the problem...

i am happy with my injen, i wish you guys luck with your AEM

 

I'm not sure on the complete severity of the choking, but I know it isn't good. Not sure how long it will take to start to show signs of excess wear and tear.

Here is a giant thread on the airbox mod. The one posted ^^ for some reason isn't working for me so here it is again.

Does anyone know if these issues happen if you get the GMS1 tune? I wanted to get a better intake, but I didn't want to go though all the pains it sounds like others are.

 

These issues happen with the AEM intake whether you are stock, tuned, modded etc. It does not seem to matter.

 

How about the stock elbow to AEM tube with a K&N filter?

 

I am thinking about running that kinda set up but I dont really care for K&N filters. The only reason I have a K&N drop in is because no one else makes a performance drop in for the stock airbox.

 

I was dicking around in the garage and I put some extra hose clamps around the outside of the AEM coupler at the bends. Well It appears to stiffen up the bend and this may resolve the issue. I will try fitting it and driving it when the weather gets nicer...snow on the ground now!
