Default When Deleting EGR...

Do I also remove the vacuum feed hose and the selenoid? or just that big valve? I just got my block off plates in the mail as well as my plugs for my A.I.R.

You remove everything and put a Vacuum Cap on the little barb that is on the Intake. You can even clip the Wiring too.

Unless it's tuned out you are going to get a trouble code if you unplug the EGR solenoid. I've read where people have capped the manifold vacuum port and kept the solenoid plugged in...

I'm about to get rid of my EGR and AIR completely. I just got some Hooker super comp LT's..

I was wondering though, I've seen the EGR block off plates that have just one big one (on the back of the intake) or 3 seperate plates.

I know the big one goes on the back of the intake, the oval one with 2 holes goes on the stock manifold, or header if it has the fittings, but where does the other one go?

What I really want to know, is do I need all 3 or just the 1? My headers don't have any emissions fittings.

The one with one hole goes on the header itself, but it you got the off road ones there wont be a hole to block off EDIT i read wrong, the third one will go on the other side of where the EGR tube hooks to the mani
