Dang David. I just recently bought some for my 97 at O'Riellys for $6.50 each, listed for $11+. That's almost twice your price. Yes they are designed to last 100,000 miles but I got sick at that price.
Too many people have said the same thing about running a different plug than AC and having issues for me to consider running anything else.
