EGR Valve specs
I bought an EGR forgetting that theres two different specs. Unfortuantely for me i bought a cali spec valve and my supra is a non cali spec. My question is are there any differences, internal wise? I know that the cali spec valve has an extra hole that i covered up with a screw and some silicone on the rim. Im just concerned about the internal structure and what effect it will have on my vacuum.
