I've heard that the stock replacement coil buzzes pretty loud. Get the MSD square looking universal one with fins on it that is $10 less than the stock replacement one. I have that one, and it's great. You will have to drill a few holes to mount it, and cut the harness to wire it directly instead of using the clip though. I read a post once by a guy from MSD, and he said that one was supposedly a little better than the stock replacement too. Better and cheaper sounds good to me.
