    The Iridium plugs are superior.

    Iridium plugs are superior and last the longest but the retail cost is often high. Labor to replace the plugs is .8 hours. I have had good luck with Denso platinum plugs but dislike Bosch Platinum its all down to personal preference and how often you are willing to change the spark plugs.

    Why don't you put in what the MANUFACTURE recomends. That is what they designed the car to operate with. The MANUFACTURE recommendation for replacement is 105,000 miles or 7 years which ever comes first. That is based on a properly running engine.
