What makes you think they will go? I have 260,000 miles on the original COP's. I see no reason to replace them, the truck runs as good now as it did new. I probably have 5X as many engine hours on my truck as a normal truck would at 260,000, since I farm with it. It idles all day some days.
If you have that mentality, then why are you on your original pistons? They'll go someday too!
I'm just kidding with ya. But seriously, there's no reason to suspect them over any other component.... If you want to be paranoid, you should replace the fuel pump. It is mechanical and MUCH more prone to failure than coil packs.
But I've seen new ones take a dump in 200 miles so....
There's a saying that I like.... Tried and true.... Well you coil packs have lasted 50,000 miles- That's purty good reliability. Who's to say they won't last a million? If you replace them, then you are putting an un-tested set in your truck. They might die driving out of the dealership!
Don't think I'm making fun of ya, I'm not. I just want you to think about it. Maybe it'll save you a few hundred bux.
