Would there be any concern of this intake cracking when it flexes at a very cold temperature? I waited a long time for this intake to come out. Whether normal or not I'll be waiting a while to pick one of these up and I can totally understand why others would be hesitant as well.

This type of composite isn't really effected by temperature, so whether it's 120 degrees, or 20 degrees, it should move the same and hold up the same. Although, time will tell.

I've been reading this saga for a week or two now. I read somewhere that you've returned it. Our guys took it back for you correct? I wanted to make sure we handled the situation since it sounds like other outlets were no help. I skipped about 5 pages, too... so I might sound out-of-the-loop, here.

I don't think anyone who decided to return theirs have had any problems doing so from any of the vendors. At least not that's been reported in this thread anyway.

WILL YOU please stop...omg... Because of you I have checked several times...the freaking thing moves WHEN you first apply the throttle=NO VACUUM then returns back to the correct state while rpms are dropping. GO PUT YOURS ON then rev the freaking thing and SEE with your own eyes ITS NOT VACUUM.... people are getting mixed answers on here. And you of all people have no experience with it because yours is STILL IN ITS BOX..... go do that before you post technical experience with a product you have no knowledge on except in someone elses videos.... thank you

Apparently you are not old enough to remember the days of vacuum windshield wipers...they worked fine until you floored it to pass someone and the vacuum dropped. Also, if you ever had a vehicle with a vacuum gauge ('78 Dodge 1 ton, with towing package and vacuum assist trailer brakes comes to mind), the gauge drops when you accelerate. This is because the engine develops more vacuum at idle because it is pulling against closed throttle blades. When you open the throttle, the vacuum drops as the air is allowed free passage into the manifold. I propose an experiment, mount something solidly on the engine (valve cover, etc.) to measure the position of the intake at rest, then crank the engine and see if it moves...

I just noticed this issue with mine and I'm only full bolt ons and cammed. I hope all goes smoothly as far as retunring or what not.

Would this flexing affect the air travel/velocity and possibly performance..? I wasnt very impressed with dyno numbers granted the weather was totally against me compared to the last dyno

No it won't. At WOT the intake is in it's natural state.

So i've been following this for awhile now and a lot of it has been kinda funny. I've agreed a lot with 19Cobra93 has said in the last couple pages. And i've come to notice after some checking on things .. for those who have a Steeda Intake, do the same tests.. where you would " blip " the throttle real quick .. you'd see the same effect with the black plastic.. Anyways.. good luck guys!

Well since your talking about the CAI, then I highly doubt there is enough vacuum inside the CAI to make the plastic deform when you blip the throttle, I think you are seeing things.

The plastic CAI elbows are not going to flex under vacuum. Maybe the rubber ones, like the stocker, but even then I've never see it happen there either.

My steeda CF elbow is pretty hard. It would take more vacuum than any car engine can make to deform that thing.

First off, vacuum only occurs AFTER the TB. So nobodys CAI on a N/A engine should be "flexing" or whatever unless you have an extremely dirty/clogged air filter.

You should see some of the K&N style filters that the guys run on their truck on the pipeline, I have seen some so bad you could barely see the pleats.
