I figured that out, as you posted in my other thread.....which i figured out before you had posted after looking online. Thought i was told they were ultra red, and then looked in my messages and he said just red wires, so i had looked them up and found out they were something different, and i prefer my ngk's over these as these do not like my car, but run on regular de's and shit fine. Thanks for trying to help miko, even though i had already posted in the other thread you posted in 3 days ago that i knew then they were not.
