In my case I coulld tell each time the breather hose would slip off... this was both before and after the tune. In addition, Vince had do perform extra tuning (via data logging) due to a/f ratios which the car was seeing with the CAI installed. The tuning has actually appeared to have solved the a/f ratio problems caused by the intake (couldn't find any other source)... The only other issue resulted from the breather hose disconnection...
Btw.. Hahn has contacted me about the connection... I explained that I fixed it by lengthening the nipple, but all the extra hardware looks like crap (however, not as bad as other home-made remedies might have)... I will be happy to give an update to everyone should I hear anything....

There is a problem if all these people are having problems. You can deny it all you want but until you add a clip or latch, the problem will be apparent and people will continue to throw CELs like I did for running lean at idle. I took the intake off and went back to stock and BOOM no CELs anymore and I have a Trifecta Tune
As previously mentioned, no clip is needed, and unless the tube disengages itself, no leak is encountered. I am confident we can alleviate this disengagement for the few who have experienced it.
As for why your car's unique combination of tuning and components led to an issue, the best thing I can tell you is this...bring it here, and we can put a tune on it that won't be troublesome with your combination! Until that happens, we simply cannot account for any and all possible combinations, and do not market the product as perfect no matter what combination is employed. Barring that occurrence, our offer of a refund remains.
All I hear is lip service and I for one am extremely glad I did not get the Coolram intake. Those CELS are due to a leak at the breather junction on the intake. The nipple is smooth and does not lock on like the stock fitting that is the issue. Those lean codes dont occur with the stock airbox but happen with the intake on stock tune so it is not the tune causing the issue in that case.
Nonetheless, I'd prefer to work directly with our customers to alleviate the very small percentage of instances of the tube separating, than argue our engineering capabilities with someone who does not own the CoolRam (although I do appreciate your using our downpipe!). I am sure you'll agree that's the best use of my time.

You are certainly entitled to your opinion, and we to ours. We will simply have to rely on our depth of experience and direct consumer feedback from hundreds of successful installations to develop ours

You are incorrect. The seal is performed by the O-ring inside the fitting contacting the tube OD. It seals irrespective of the retaining lip's presence or lack thereof. No leakage occurs if the tube does not disengage from the fitting. I've worked with these fittings for years, and I'm quite familar with their function. Take a look inside the fitting and you'll understand the function of the O-ring better.

Ok here is what i know, i know i threw a code cause mine hose poped off, i know after i made my own clip on there to clip the hose onto, it doesnt pop off anymore and i have no more code, we are all argueing back and forth, the guys who bought the fist intakes from u that had a clip on there to keep it on all say they have no problems with it coming off or with it throwing codes, all us guys with the new type are complaining, so why dont u just put something on there again so we can clip it on and see what happens, see what the feed back is, then we will see where to problem lies, if no one complains anymore, it was ur lack of a clip that was the problem, if we still complain then it is something else that is the problem. So instead of us all getting into a big fight and ending up not wanting to buy from u cause of u refusing to work with us and try some ideas to solve this, why dont we work together and solve it right. Doesnt matter what other types of cars did with this, this is a cobalt, and its not other cars and its obviously not doing what the others did. so please help us solve this without fighting back and forth, just give some new clip system a try, i volenteer to test one if u make one available.

If you review my lengthy explanations, and they still don't work for you, I am sorry...I've tried to be as clear, honest and informative as I can. I can do no more than that. While I'd like to make you happy by just agreeing with everything you say, to do so would be just a band-aid to make you happy. I prefer instead to engage in an actual discussion, present detailed explanations, then offer real solutions, all the while hoping that everyone can benefit from the data I am capable of providing. (You too should examine the intention and internal construction of this fitting connection, and you may indeed discover that everything I say is true.)
As stated, we have a solution we're working with relative to the several tubes that have disconnected, and we've adopted a production solution going forward. We'll work with every customer until they are satisfied...that's always been our track record to date, and it will remain so. As I am confident that my explanations here have been complete and concise, I will return to that most important role now, working directly with the customers. Should you remain dissatisfied with our product, please return it for full credit. Thanks again for your feedback!

You bet! Anyone who's had trouble with one disconnecting will receive our new version that will stay attached. They need not create their own solution, I'm currently working with the several who have indicated a problem.
