robert I know u liked them could u actually tell a difference | I was getting a high RPM miss with my mods. It went away after installing the Iridiums, so who knows. They're not that expensive and since you plan to change them anyway why not go for the good stuff.  |

well are you experiencing misfires?
no? then why fix what is not broken.
and the long life platinum plugs have been known to last beyond 100k easily. |

Sometimes they're not 100% from the factory. At 80,000 miles you're at the bad end of a good tune IMO. |

My '04 just turned 34,000. I think the national average is 12,000 to 15,000 per year. So I'm lookin' good.  |

Way more than my car, but still not out of control. It could have been an early 03 and been on the road for a full 5 years. |
