Its worst than I though it would be...way worse. I spent over an hour nearly matching it...but didn't do it 100% since I will have the plenum off later to bore the TB out anyway. 2 of the runners have an obstruction from the bolt holes, not sure how much you can grind them down. It also has a casting ridge down the sides...total pain in the ass. If I had 650 bucks, extrude hone would be doing this piece of crap. Oh well, its so much better now than it was, and the lower intake was already done.
