Question about AFE intake

I have a AFE Stage 2 CAI i am about to install it i was wondering use red plug or no plug? Also do you need to reset comp after install?

 

Ok Left plug out it is loud, will putting plug in quiet it down a little? Heres some pics of finished product i made plexi cover just for fun

 

i leave mine off. but my truck is loud as hell anyways when you get on it.

 

I didn't feel it was necessary to make a new thread so I figured I would piggy back off of this one.

After the install of my Afe cai i had 2 remaining bolts that held in place the OE air box. Now, there are two open holes from where they came. Should I put them back or leave them off? I suppose my question is will anything be damaged if they are missing?

 

nope just leave them off, nothing will get damaged. Keep them though so when you go to pass smog, or sell the truck or sell the intake you can put them back.

 

Thank you for the quick reply.

 

Yeah sure, i just feel there is less stuff to fall off this way

 

Personally I put them back in unless they intefere with something. If I don't do this then a year or two or three down the road I don't have to try and remember why I have 2 bolts stored away somewhere, that I can't figure out where they go, or why I saved them.
