Any hemi spark plug options?

Didn't see any threads on this. Is there an option that will either last more than 30k, give me more Mpg or more hp?

Re: Any hemi spark plug options?

am guessing not much has changed in the hemi form the WK, and on the WK running anything but BONE STOCK COPPER CHAMPIONS threw codes and ran like crap.

stick with the OEM plugs and intervals./

Say what?

I'm an old Ford guy so I've never owned a Chrysler Prod., much less anything with a HEMI. But I just ordered my WK2 on Dec 31st.

But the HEMI needs new plugs at 30k? Is this right? Why?

They aren't iridium or platinum, coppers need changed at 30k. Plus there are 16 of them at $4.50 each.

No other "good" options right now.

I was shocked when I read in the owners manual about changing every 30K miles!

I paid $42.00 for 16 plugs. Changed them myself. Pretty easy, and I am no mechanic

EXACTLY, it's simple and easy and you should be able to find the copper plugs for ~$2.00 each * 16 = $32

Oh, BTW, in a stock motor NO spark plug will give you more power or more fuel economy so the ONLY reason would be for extended life. BUT, if you get 3 times the service but the plugs cost 3 times as much your even.

A quick search on the net seems to show that many have used the platinum's on Dodge 5.7's without issue and that should push the interval to 100K. They also say to stay away from iridium (thin wire).

Re: Any hemi spark plug options?

Any new updates? I'm approaching 30k on my 11' JGC 5.7 and wanted to know anyone have any good or bad feedback with any specific plugs.

Thanks,
Jason

I decided to try the Champion Iridium 9055 plugs and will be installing them over the weekend. Stay tuned...
