Speed Demon, old skool Twisted Wedges did NOT say Trick Flow on them, I had a set that had serial numbers that were only 3 digits long, and there were no external markings to let you know they were anything different than a plain old aluminum GT40. The only way to tell was the signature TFS water jacket around the spark plug. Just an update.
I bought two sets in the past four years, in 99 my first set didnt have them on them and just bought a set a few months ago, and they didnt have them on them either. I just thought I might have gotten and old batch. I know the track heats have the Trick Flow logo on them.
