Dammit! Screwed up my cai install

Just installed my CAI intake. The intake end were pretty big and after trying to force it in, it made a whole on the piece pictured below. Was gonna hit the track tonight but not with this big of a boost leak. Any one know of a way of sealing this up maybe with epoxy? or what replacement piece I need?

Thanks for any help

Yikes. That looks like your turbo inlet pipe. I believe it's all one piece back to the turbos and requires dropping the motor down to replace. I'd get a tigh silicone coupler to fit over that leak and try to clamp it at both ends for now. It's not ever under boost so you don't have to worry about it blowing off. It's the inlet.

No boost that is just the inlet, so the only concern is anything being sucked in there, dirt etc, you could probably even just wrap it well with some high heat tape to keep anything out for the time being until you can replace it (that part is like $120 which sucks)

Definitely sounds like a job for black duct tape

The only real fix is buying the OEM part which I think is just over 100.00 bux.

You could also just fine a silicone hose coupler. A lot of speed shops carry silicone hoses.

Part is cheap but to actually change it out its a PITA for sure....I would just go the truck U route but get it in black color instead of the blue...Much better than the duct tape for sure...I think its plastic shrink wrap...I would do this method over changing out to a new one...It will definitely hold as others says its sees no boost but just air going in..

The rescue tape posted in the video above will work, I've used it before and it works just like they claim. We also use if for temp fixes for ground equipment in the Air Force. I like it because it only sticks to it self and if done right it will create an air tight seal.

To change out that inlet tube is a PAIN! However, you will have no boost leak as that pipe is not pressurized. You could still run at the track just tape it up temporarily.

you could cut the leftover end off "the clamp end" and stick the filter pipe in whats left over and clamp it.

Just make sure if you're using tape that the surface is good and clean. It will be a short term fix, if it gets sucked in you'll need a turbo too. The front pipe isn't bad, the rear one is the real pain! Calls for engine removal...

That tape will last a long time. Also available as "self fusing tape" at McMaster.com. Much better for electrical use and abrasion resistance.
