      Comments about Bosch OE Fine Wire Iridium Spark Plug:

      Iridium came stock in my Pontiac Vibe & Mercury Mariner Hybrid. Both lasted 150,000 miles & would have lasted longer, but I changed them out anyway. Now in 1998 Lumina & hope to never change them again in V6 w/ 3 hard to reach against firewall.
