...its a black 2"x3" black plastic cover on the front right sideof stock upper intake is leaking. On the Cobra intake its just a round2" plug, similar to block freeze plugs. I noticed carbon residue that you see on exhaustconnections when you have a leak. What the hell is this thing...i always wondered[&:].

most dont even have that thing lol its just a cover for nothing....

No i don't think so...theres a trail of black smoke from exhaust leaking there. It looks like it is held on by double sided adhesive tape or something.

I would like to see a pic.. The only thing i see that looks like a freeze plug on my intake is metal not plastic..

Thats what i see on Cobra/GT40 and other intakes. I'll see if I can get a pic tomorrow.

umm if it is what i think it is...... that IS just a cover that has NO use
i know it's about the same as this since i pulled the intake off my fox and never took pics when it was stock, but this is my 95's it has the indention for it like my fox did is this where that cap that you're talking about is?

if so then.... yes i am right and it has no use.... i never had the thing on my fox or my sn

i'd like to know how exhaust is coming out of your intake....

redpony88

lol yea me too

camaroeater

Yep thats it....thecoverhas alway been loose, but I have never seen a trail ofresidue that looks like its blowing out ifthe top of it. If a cap is behind it, I'll just take it off. What the hell is this capfor anyway.

if that cap is an opening into your intake and you find carbon there, that is probably blowby oil from your PCV system. In other words, your PCV is throwing oil into the intake and that oil gets carbonized from the heat and oxygen present in the intake. What you are seeing in your intake is not exhaust gas but carbon build up from oil vapors.
