Well, after 2 years of kicking the can, I ordered the plugs from autozone. BTW autozone has an online special where they will give you a 15 dollar gift card with every 100 dollar order. They sell the pulstar iridiums for 12.99 each (9.99 for plat). Free shipping on every order over 100 dollars.
I am also doing a cap and rotor change SO I will change the cap and rotor, drive for a couple days, then put the plugs in. Right now I am running the accel u-groove copper plugs from the truck tuneup kit. I did a tuneup 2 years ago and about 6K miles ago (Yeah I don;t need to drive very far to work, and I have a motorcycle).
I will give you guys a fair review. If they are not noticeable, then i will just smile at the fact that they come with a lifetime warranty. SO, for 12.99 per plug, they will pay for themselves as I intend to drive my truck until I cannot fix it anymore myself or the cost of repair is over the trade in value of the vehicle. With only 55K miles, she has a long life ahead of her. Forget rust, Zeibart has my back on that!!! I have 5 years left on my extended warranty (or 45K miles) so the tranny should not be a huge problem as they tend to have problems at 70-90K at the earliest.
I will add to the thread when I install them
