I have read on here and other sites, and it seems like the forge plate is what most run. I stumbled upon this on ebay...
Ebay Plate
This one is the same shape, but lacks the o-ring the forge has..
Then there is another one that is thicker...
Thicker plate
But the forge plate has the o-rings, where these other ones do not. What is the reason. Why pay $40 when I could pay $15??
Should the o-rings create a better seal?
Also side question, when blocking this off, to run a cold side bov, do you just disconnect the plug at the bov so it doesn't try to function?
