Best Plugs for the 5.9

[Bigtman07]

Ok every forum needs this thread.

What are your thoughts and recommendations.

I have always heard that the copper champions work the best. I won't deny that as I used the platinum and had pinging issues. So I went back to copper.

Anyone else have better luck out of NGK? I have also been looking at the E3 but I need a good cool burning plug. I wanna keep my cylinder temps down for when I run my tunes with 93 octane.

I have a 3rd Gen so I am not sure if its apples to apples but here is what I found. I ran the stock plugs. They were good. I ran the NGK and they were about the same but didn't seem to last as long. Then I tried the Bosch Platinums and they were horrible. I now run the Champion Platinum not the double ones. They are the best by far! I do not think I will try another plug again for the Dodge. Just my 2 cents.

^^^Good to share! I know there are mixed reviews on all the plugs and I really wouldn't mind an overall idea of what works best. I had platinums in there but they may have been bosch now that I think of it.

Good thread to start Tony, I'm bout due for a plug change

 

[Joshwaa]

Yea I can not figure out why but the Bosch Platinums we just no good. I have used them in my previous Chevy SB's and they were great. Tried them in the hemi and they were worse than the old NGK's I replaced. I would like to know if anyone else had the luck with the single platinum Champions like i did. BTW don't know if it's still going on but I payed 3.18 per plug and they had a rebate for 3.00 a plug. Yea got a whole plug change for $2.88!!

stock champions.

I used to run Champion truck plugs untill they stopped making them. I just run plain old copper champions or whatever thier regular plug is.

i too would suggest the champion copper plugs (RC12)...or Autolite 3923 if you're really wanting a colder plug.

I'm running some copper NGK's in mine now. Had them in for about a year and they're still doin just fine but I'll probably swap back to Champions and see how they do
