Any info on plugs to use, and can it be done at home? Shop is $$$$$ and thought id ask you guys/gals. Larry

 

There are not many plugs available for the hemi that I have been able to find. Most likely best bet is to buy the mopar plugs and change them yourself. On my Durango, I have to take off most of the intake to gain access down the left side of the engine. With 2 plugs per cylinder you also have to take off the coil and the second plugs is located underneath of those. Its a good afternoon project to work on.

 

A couple I found all gapped at .45

DOes anyone no why dodge ran copper plugs ?

I thought copper was only for turbo or supecharged vechiles?

I was thinking about chaning plugs to champion 3570 in a 05 4x4 hemi.. Or do you think the stock copper plugs are best..?

Or should i 1stage colder if go with plaitum?

 

Everything I have read and heard says to stay with the Cu plugs. The 5.7 does not like platinum or iridiums. I was also told it helps to take the brake booster loss so you can get to the back plugs on that side.
