Doesn't allow hot coolant to pass through your EGR for 1. Keeps the air flowing through your EGR cooler. As for gains. I wouldn’t think you would notice anything.

This is totally untrue. DO NOT unplug the coolant lines from the EGR spacer. As "warm" as the coolant is, the exhaust gas is much hotter. Leave it connected.

That used to be the conventional thinking back in the early 5.0 days.....but some magazine disproved it. I'm sure the first person that lost 4 layers of skin after touching intake up by the TB figured this out as well....lol

I've done that to my car...maybe I should hook it up again lol. I seriously doubt that the difference in either case would be noticeable at the track or on a dyno lol

if you have bypassed the EGR then you can bypass the coolant lines. If the EGR is still operational, bypassing the coolant lines would be a step backwards, because just as stated earlier... even though the coolant is hot as hell, the exhaust gasses in the EGR are hotter yet.
