Default AIR and EGR block offs?

I want to disconnect my AIR and EGR stuff. I just need to take the AIR pump out along with the hoses, then block off the passage I left that goes into my headers correct? What do I block it off with? Is there a certain AIR block off plate that goes into the header? I have Jet Hot LT's. I need to use these hoses for something else, I have the EGR and AIR deleted from the PCM. With the EGR block off plates, I only need 2 right? And both of them are on the drivers side of the intake manifold? One of the EGR tubes connects from the drivers side of the intake manifold to the passenger side that has that little tube that goes into the headers right? I just need to know what I need to block the AIR off with. If I remove the AIR pump will I need block offs for that as well?

make your own
when you pull the piece off the exhaust manifold, take the flat piece with the hole in it that the ribbed tube went thru off. make a small piece of aluminum or whatever about the same size as that with a hole in it for the bolt too be screwed back into the manifold. use some high temp RTV too help seal it

do the same for both openings on the back side of the intake

dont buy the block off plates when you can make them for free

when the air pump comes out, you will need too block off both openings at the maniflods and one on the intake tube

No I know how to take everything out, I just needed to know if there is a special AIR block off that I need. I know how to take most of it out, I found a thread after I posted this, but I just needed to know if I need to block off the AIR tubes when I remove it off the headers.

Does anyone know the size of the vacuum cap needed for the CAI? It's a LPE. I know I need a 5/8" vacuum cap for the line that went into the intake manifold. Does anyone know the size needed to fit an oil drain plug into the headers?

Thank you. Some people told me it could be an 18M too. The bracket that held in the AIR pump can be taken out as well, correct? It's the big bulky silver bracket.

I just cut the AIR tube behind the header primaries and there is stuff SQUIRTING everywhere?!?!?!??!?! It isn't oil, coolant, or ANYTHING, it smells and feels like water. Is this normal? Is there just water pressure build up? Gah nevermind. I acidentally cut the A/C line which is right next to the AIR tube How do I fix that?

damn lol
you will need a new AC line, or just yank that **** too (winters coming anyway)

you should cut the AIR line where it crosses underneath the crank pulley and when its loose there, follow it up and cut it again farther up on the passenger side

I think you use the search button to block those connections off.
