I have installed headers. Going to put an M22 plug in the headers to plug where the air tube fits into the headers. I will also block off the rear of the intake manifold. I think I will be leaving the EGR untouched. Any other steps to deleting just A.I.R. Any problems with this. Thanks

Its been a long time since I deleted mine, only other thing I can think of is it will probably set off the check engine light. I know I had AIR programmed out of mine when I had my programming done. Really helps clean up the engine compartment.

 

if u delete air, might as well delete egr too, since your state dont have emission test I think.

 

The rear of the intake manifold and that tube on the rear passenger header is the EGR. The two things on the front of the headers and the hose that goes to the air intake by the maf is the AIR.

 

thanks for the info. This Vette is a lil different from F-body. Basically I want to delete the AIR tubes coming up out of the top of the headers and back into the back of the intake. Was gonna make a small block off for that. Didnt want to mess with making an EGR blockoff plate for now so thinking of leaving that part of the system alone. Any issues running like that. It has a stainless steel hose coming up from both headers that run into the back of the intake.

 

nope shouldn't be an issues at all. AIR was designed to heat up the cats quicker so getting rid of AIR might sacrifice a little long term life out of the cat converter. FYI
