That is what I paid for my last set of Autolite Iridiums, after rebate about $3 each.
I love them. 1st set had over 60K and started like I just put them in.

For the average passenger car that will see no more than a couple 100000s of miles in its entire life, it may be a waste.

I love the Iridium plugs in my 96 AWD Aerostar, when I used double platinum they would quit starting the vehicle quickly at 12-15k, I have gotten well over 60K on same vehicle with Iridiums and it still starts like the day I installed them.
