I didn't log on looking for info otherwise I would have used the search function. Like I said, so far so good in my car, THAT IS A FACT. I have used the CORRECT NGK's and Bosch Platinium and even now the IRIDIUM's and all work absolutely FINE. Someone asked if there was iridium plugs and I just passed on the info. I didn't ask for anyone's OPINION on whether they worked or not. I also never said everyone has to have them, if you prefer NGK's, cool. The iridium's were a tryout basis and so far I am very pleased.
