I don't think you understood what I was saying. I'm fine with the looks. What I'm not fine with is hurt performance. Let's say I cut into the stock hood, and install the vent. Then I test it, and find out that I placed the vent too far back, and it's actually sucking the air in. Now, I've got something that hurts the performance, and I have to close it back up. In either case, the hood has to be tossed and replaced, but if it's a 20 dollar junk yard hood, I'm not going to care much. If it's my stock hood, which already has good paint on it, I will care a lot, since now I have to go get another hood and get it painted to match.
