    Iridium Spark plugs

    Has anyone used them? What is your impressions of them? Which ones are you using A/C Delco or Nippondenso?

    I am using the NGK model and thus far (2 years old aprox. +5k) they are still very strong.

    I am cheap.

    I just replace my regular NGK TR55's every 8K or so miles. That takes me 2-3 years to get so....
    From what I heard the iridium just last longer. No experience with them though.
