Default What plug to use for EGR hole in intake?

IM removing my EGR system this weekend and I all ready have to block off plates but was wantting to know what kind of plug to get from pep boys to block off the hole in the intake? I did a search and all I could find was something about getting a plug from pep boys. Which plug do I need to buy?
thanks, justin

A rubber expandable freeze plug will do perfectly. It drops right into the manifold top hole and when you tighten it up, wont leak. I ran like that for months prior to tuning. When you take the EGR tube off the intake top, be careful not to drop the rubber O-ring underneath the fitting into the intake.

I think it was a 1-3/4 rubber freeze plug on mine....rubber seals a little better than the metal ones in this case....and because you can tighten it up...I feel safer about it staying in the hole...although....either will be fine.....and you really dont have to worry about either one....

The GM part lists for $15.71. I found it for $8.72 from an online GM OEM parts discount warehouse.

i paid $11.32 for the gm part
all it is, is a metal plate that covers the hole, but has a plug with an O-ring in it
works great

The freeze plug I got cost me $1.99 and it's been working out perfectly.
You COULD take the old EGR off, chop the metal tube, bend it over and hammer it down about 3 times, and bolt it back up, it works, but it looks like you have a horn coming out of the top of the intake, we did this on my car so I could drive the car home, the next day I got the freeze plug and took a whoping 5 seconds to put it in.

Your welcome, I favor the look of the GM part too. I do agree that the freeze plugs do the job quite well also.
