2011 Ram 1500 Outdoorsman 5.7 Hemi. I Have 54,000 on it and would like to replace the plugs. I am getting mixed opinions on what plugs I should use. What is going to have the best reliability and performance?

 

I switched to autolite xp5325, they have been great so far. It's a spark plug though, anything in the correct heat range will work fine.

 

I run the regular platniums in my 09 , 185,000 miles
1st change around 48,000 from the orginal plugs
150,000 2nd change

 

OEM plugs should be fine, never had an issue with the oem plugs in my 08 Hemi.

 

Autolite XP5325 (autozone/autolite also has a mail-in rebate for $32 for 16 plugs)

Rebate: http://contentinfo.autozone.com/znet.../en_US/559.pdf

 

My factory ones were all NGK. They hardly look wore at all.

 

I get this question alot, I tell the same thing, chevy dodge ford, etc.....I always ask how many miles are on it, they reply xxx,xxx, then i ask what type of plug was in it, then they tell me oem...ac, NGK,Autolite...I tell them put the same thing back in there... it got you this many miles didnt it?, and just like the OP, the correct heat range makes all the difference in the world, I am not saying there are not better plugs, but the stocks get you there and back for a lot of miles...so use them

 

I do have to agree with you somewhat BULLRAM, (when it comes to OEM on certain items) but when the dealerships jam it up our azz`s on the price for the OEM plugs, most of us will always find a substitute that will work just as good if not better sometimes. And right now, autolite has a very tasty rebate going on. I`ve used autolite plugs over NGK plugs every chance i get. The NGK plugs seem to foul quicker than any other plug i`ve ever used... and they never lasted that long for me either.

 

I'm searching for plugs now too. There doesn't seem to be a lot of options.
All I've come up with are:
NGK 92174 (LZFR5C-11) @ around $5
Autolite XP5325 @ around $6
NGK 97606 (PLZFR5B-13E6) @ around $13
Autolite APP5325 @ around $6
I also found the Autolites rebranded as Nascar Advantage, but way over-priced.

 

SO which did you decide on? Any suggestions? I'm about to make my 30K service on my 2011 Laramie...
TIA
