So i still have the 606's in my car and I have stumbled upon a misfire. Since I am no longer stock everyone says to get the Autolite 104's Autolite Copper/Spark Plug (104) | AutoZone.com

Please let me know if these are the right ones cause autozone says they wont fit.....



Any help is appreciated, I couldnt find a thread with a direct link to correct ones from AutoZone.
