Hi
I pulled a spark plug on my wife’s 2014 1500 5.7l with 185,000 km to see what it looks like. She hasn’t been having any problems. I know it’s overdue to have new plugs according to the maintenance schedule. But it didn’t look like an overly worn out plug to me. But then again I’ve never looked at one from a hemi and have minimal experience looking at others too. What do you think. Change them anyways - before they do start to cause problems?

If I do replace them would you put the same back in?
Thanks for the help.

I would probably change them if it was my truck, and yes use the same plug. If you do change them yourself, the trick to get the plugs out/in on cylinders 3, 5, and 7 is to use 2 universal joints together on the plug socket.

They're definitely worn. If you already pulled them out...mine as well put new ones in

These engines are easy on plugs as long as there are no problems with it.
I would definitely replace them with the exact ones that the manufacturer recommends.
Most of the fancy expenses aftermarket plugs do not work out very good.

I just had mine changed at 150,000 mi/240,000 km. They didn't look much worse than yours. The engine was running fine but I didn't want to wait any longer and risk having a ceased plug in the head. I would change them since you have pulled them and not wait longer. But where are the other 8 plugs? There are 16 total. The other 8 on mine showed more wear. Definitely use OEM replacements. $200 for plugs seems like a lot compared to what it used to cost for V8 plugs back when I was younger. But those plugs didn't last a tenth this long.

Not to mention they didn't use 2 plugs per cylinder back then

I would change them, 185 KM what’s up about 150,000 miles just guessing. Zooming in it looks like they’re worn to about 40,000‘s when the gap should be less than 35.

I replaced the ones on my 2010 Ram 1500, 5.7L Hemi with 200,000 MI + with E3 diamond fire plugs. The dealer installed them for me after I purchased them online. The 2010s did not come with 100,000-mile Iridium spark plugs and the dealer would not supply them. If E3 is good enough for NHRA, they are good enough for me.
