Well, I googled them and they go for $6.58 low price. So, this guy's price is "normal" within range. I just replaced the plugs in my echo to iridium but used the Denso and they were $16 each at Autozone (Southern California). The NGK Iridiums were, I think, about $6 or so, but I just got the Japanese brand. My 06 AC has iridium plugs in it. You should check with Autozone or Pepboys, etc. 1st and see how much this model plug is---why wait for shipping if you can get it immediately? Make sure they are good for your truck..don't believe anything you read on
ebay, double check! Also, I don't see how the guy claiming that the normal price is $149...that's way too much. I would just get them at an auto parts store so if you have to return them, it's no big deal.
