Is there a specific reason the HEMIs prefer to have plain old copper plugs put back in?

Just swapped mine for the same thing that came out of it. I think the main thing is that they run fine on the plugs that cost less than 2 bucks each and that's what the manufacturer recommends. And why pay more and use a longevity plug if you still need to change it every 30k?

I don't know of a reason but some guys have put platinum plugs in and said it didn't run well w/ them. On the other hand some guys have the platinums in and it runs fine, but the consensus is that the plain old champion coppers are the best.

Just kinda strange to me. It seems like with how much of a pain in the butt changing the plugs is, and how much of a more complete and efficient burn the newer style plugs have, that it would make sense to upgrade to a plug that performs better, that doesnt have to be changed every 30K.

Was just wondering if there were some specific reason related to the HEMI that made the plain old copper plugs better.

Not sure the science behind it, but apparently the Hemis are engineered for coppers. From what I understand, and I may be wrong, the way the factory specd timing and spark plug gaps are based off the use of copper plugs. Also, a copper plug is a better conducter than platinums. Another reason for poor performance is when people use platinums, they spec them to the same .045 gap based on coppers which means the spark will be weaker and so will performance. A larger gap is needed to compensate and then timing.

anyone used the E3 plugs that are out? yeah or nay?

i hear a lot of hell no's from the camaro/firebird/corvette community. but i use delco iridiums in the camaro and the ram has stock replacements.

Stock replacement plugs here.

Gonna go stock as well....I like workinn on a truck beats watchin smellavision.

LOL.... am i missing something????? i hear people saying 16 plugs..... is there 16 plugs for a v-8 these days????? WOW.... if that is the case....
