Cracked intake manifold?
Installing a new air intake, didn't realize the bracket needed to be removed as well before putting the new backplate on, and when screwing in the filter mounting screws I heard a pop. Upon inspection, the intake manifold has a line on the inside and outside, I can't tell if its just the powder coating or not. How much of an issue is this? I rode the bike afterwards and it seems fine.

if it is just powdercoating from the part being tweaked,your fine.. that most likely isn't the case, there shouldn't even be any coating on the inside. if the manifold is cracked, if you are lucky it will just run bad or stop. it can suck air and run full throttle, then the only way to shut it down is the ignition.. you should get it checked out and replaced before you run the engine

This seems to be a common problem, I've read several posts about cracking the induction manifold while upgrading air filters.
Are the instructions unclear? Did you read them? Seems odd so many people are doing the same damage to their bikes. Maybe there are no instructions for these air filters?
Smear some JB weld over the crack and smooth it out good when dry seems to be the consensus idea without buying a new part.
Good luck.

Yes, the instructions are VERY unclear. The instruction diagram shows the bracket in place and does not mention it needs to be removed. This is mentioned in the text, 3 pages on!

Here's the issue, with the other screaming eagle air intakes, you retain and use the support bracket. If you try the same with this round cleaner, then you will end up cracking either the back plate or induction module since its too far gapped. The only way to get it flush is to remove the support bracket and bolt directly into the heads.
I took it to the dealer, $403 for a new one, they said the cracked one would be fine for probably years until the crack worsens from vibrations. But I know it would bother the **** out of me so I took the hit and bought. Very expensive mistake.
