    I put genuine NGK iridium plugs in mine with the intention to go at least 100K without a problem. For most cars I consider a GOOD platinum plug for only 60K. For the total expected use (time and mileage) I don't consider the difference in price to be a factor. I go with what the factory put in.

    Probably not for a 2008 model. Unless you think the vehicle will drive more than 60,000 miles before
    it expires. What kind of mileage does it have now?

    If you're thinking $15 x 4 is going to be too much to spend, then you won't want to hear what you're expecting in the near future on your 2008. $60 DIY is cheap to keep a 12 year old car running like it should

    My favorite plugs on the planet are Denso Iridium TT.

    Not sure if they make them for your application, however.

    The most expensive platinum (double platinum) plug at RockAuto is $8.40
    More Information for NGK 2647
    ... Regular platinum is only $5.18
    More Information for BECK/ARNLEY Z206
    These are the "consumer favorites" for $2.35 and $2.23 respectfully
    More Information for DENSO 4503
    More Information for NGK 7090

    The most expensive iridium is $5.71
    More Information for NGK 4996
    This is the "consumer favorite" for $4.59
    More Information for DENSO 5303

    They've even got ruthenium for $7.75
    More Information for NGK 95839


    I've only pointed out the "most expensive" to show a simple point that price is really not all that important in relationship to what makes you feel good and/or secure. We're talking the price of a large pop to a simple craft beer. Buy what makes you happy.

    Are those prices specific to the Prius?

    Because I've bought more expensive iridium plugs from Rock auto! :)
