    You will have less clutter in the engine bay, but really no gains. EGR shuts off at WOT anyways, so you won't gain anything. But you will be running a hotter engine because the EGR helps run cooler engine temps and lower levels of NOx's and stuff. So, you may want to look into a cooler t-stat of you do go that route. Or a manual fan switch.

    well besides the weight and cleaning things up, deleting egr is sposed to give an extra hp or 2 and deleting the air is sposed to put less strain on your alternator when starting up the car. if you're running an ory the purpose of the air system (which affects the cats) cant be used, so you might as well take that out.

    hmmm, i'm not sure if i will get cats or not. but if i do, i would like to get the air and egr removed. I would need the codes tuned out to pass emissions right? idk if i can afford a tune, yet, but maybe if i can work a lot this summer.
