Quote:EGR is for emissions reduction right? that section above suggests it is illegal to remove the EGR
i agree with you that if the car passes sniffer what's the big deal.. but if someone wanted to be really picky i think that would be an area they could focus on
what's with no EGR? does it help performance in some way to remove it? or do you have a japanese market motor that never came with EGR (if this is the case, and its for your wrx, mind if i pm you with some Qs?)
It's a grey area.
Technically EGR is for milage, not emissions. Any emissions benefit is minor, and secondary. However, as you just demonstrated, MANY people and even mechanics don't know this. Perception=Reality, and thus... EGR is assumed to be an emissions device.
Many automakers deleted EGR from engines in the late 90's because it costs about $50, and it "only" increases milage about 2mpg. Most were adding it back in in the 00's because of milage concerns. See, it's not about emissions.
I don't have the WRX anymore. This is on my ZX3. I removed the EGR because the Pectel has no way of dealing with that system.
