Autolite Copper plugs ok?

[thecrow7841]

Hey guys, How's it going? I kinda have a small problem, so a little while ago, after reading this thread, i decided to go and check the plugs on my D and it turned out that the Mechanic put Platinum plugs. Ahhhhh, i was mad. Quick reaction and changed them. So I bought Champion Copper plugs, Cap And Rotor, Napa only had the Premium Spark Plug Wire Set. So my small problem is that the motor still sputters little but noticeable. Can the 5.2L Take the Premium Spark Plug Wires? EDIT: Any help is apreciated

No.

The wires should be OEM, or I like MSD 8.5mm Red Wires.

I have seen people install them and trough a missfire usually on #7. I would incorage you to use OEM Champion Rugular plugs, Champion Truck Plugs, Or Champion Iriduim. Just depends on how much money you want to spend. I run the Champion Truck Plug before and after my MSD ignition and really like em. I replace my plugs every year or about 10k to 15k. I can usually feel the ignition and know when it's time. But make sure you replace the plugs (OEM) absolutly every 30k.

Iridium is running great so far. DO NOT USE PLATINUM! The motors were not set up for their use.

If I were you I'd take them back period! Get yourself some reg OEM plugs for a couple of dollars more. Don't forget to gap em!

what do you gap them at?
