Now I've read that removing the coolant lines to the EGR spacer will actually make the intake air hotter since the exhaust gasses are hotter than the coolant flow. I took off the coolant lines but I will put them back if this is true, I guess I could test it for myself. I don't think it killed my performance but I didn't test the car with it on either.
Now for the EGR deletion, in my opinion, this won't give you any performance gain at all, especially since the exhaust gasses are still heating up the upper intake. I guess the proper way to delete the EGR itself is to use a phonelic spacer with no EGR passage (or other means of preventing EGR flow to the upper intake). Too bad my car is off the road for winter because I'd be willing to test EGR versus no EGR at the dragstrip.
But is it worth it to remove the EGR in the first place? The exhaust gasses aren't put in the combustion chamber at WOT. If it can add a few MPG to the vehicle, I think it would be worth keeping.
I have too much time on my hands
