| EGRs plugged just as you have done there. I have just pulled my plenum and decided to take it up a notch and I ground off the ear and the bump that sticks out on the side of the plenum along with the PCV ports!! There is not that much metal thickness on that "bump out" that is above the ear you want to cut off so take it easy when you are cutting it off or you will be at the weld shop :) Here is what my plenum looks like now with blasted aluminium powder coat that I PCed. myself
