I know a few of you guys have this done. I have already gotten my EGR tuned out and removed all the hardware and the valve out of the intake. I am eventually going to be putting my N20 nozzle in there but for the time being I just want to cover the hole... what did you guys use to cover it? I was thinking about just a small piece of plate with the one bolt hole drilled in it and some gasket sealer on the intake to keep it from leaking... any other suggestions?

 

1 3/8 freeze plug. Im using an expandable rubber freeze plug in mine.

 

damn will it work.. thats a pretty big hole... where could I get a rubber one at?

 

You can get them at any auto parts store...if your boosted you can blow those out...it will scare the **** out of you you can get a cover plate from GM that is bolted on.

 

oooh.... I thought Matt said '1' 3/8 plug not 1 3/8"

 

I spaced it cause when you type 13/8 it gets confusing, to me at least. No you need 1-one and three eights inch rubber expandable freeze plug

 

yeah, I'm a 'tard sometimes... .... plus I dont get a chance to use the "cool" smileys very often LOL...

 

Not to take this off topic, but does anyone know if the 06 Silverados have an EGR valve? I was peeking around in the engine bay when I first got the truck and couldn't see one...

 

no egr on new silverados

 

Ah, sweet. Thanks!
