Spark plug change - 2019 Ram 1500 w/ 5.7

How many miles are on the factory plugs. I would also buy champion copper plugs and ensure gap is appropriate. No need to buy expensive rare earth plugs.

Actually there is a reason - iridium plugs are used because they can go 100k miles between changes without wearing like regular plugs. I changed the plugs in a 4cyl car at 100k and they looked brand new.

The ball socket with magnet is a must, as well as a couple small extensions for the back booster plugs.

I've done them many times on Hemi's and they aren't too bad, just lay a moving blanket over the engine and lay down.

The instructions on Iridium plugs specifically say not to gap them because they are pre-gapped and the iridium center anode is much more fragile than standard.

I’ve never heard of Rock Auto. I generally don’t buy from places I’ve never heard of because there are so many fake online “stores” online these days. Not saying they are, but unless several long-time respected members recommend them, I’m skeptical of a place that sells the exact same plugs for about 50% off of everyone else’s price.

All the best,
Glenn

Rockauto has been around forever. Used to have ads regularly on prime time TV. I've shopped them for years and never had any issue. They'll usually get you on shipping but the prices are fair. Always worth cross shopping with Amazon and Walmart too before pulling the trigger on Rockauto though.

Rock Auto is good to buy from. That's why I linked them.
 
+1 On Rock Auto. I've been buying parts from them for many years.

Can you remove the fender liner for better access on the drivers side?

The problem is the brake booster/master cylinder location and extra bracketing for generator unit on etorque models so inner liner would be no help.

Never heard of RockAuto? That's the first time I'm heard someone say that in years. Like you, I avoided them at first. Then I was looking for a window regulator for my son's Pathfinder and they were the only place at the time that had one in stock. Gave them a try, and they are legit. I've bought a number of things from them since.
 
Good video. Too bad this guy didn’t put a feeler gauge to some of the plugs he removed to determine the amount of wear and show it in the video. My bet is that the factory plugs will easily go 150+k miles.

On my 2011 Ram Hemi that came with 30k standard plugs, at 60k miles, I replaced with Autolite Double Platinum. At 180k miles when a lifter failed, these Double Platinum plugs had 120k on them and were worn little considering the mileage.
 
Finally got around to changing them this week at 103K miles. The spark plug tool mentioned worked great for all but two plugs. No way to get it to fit the two right near the brake booster. I had to put a spark plug socket in the hole, then attach a short extension, then a swivel adapter, and then the ratchet. I did those two and the back two on the drivers side first, and those 4 took about 2 hours and lots of cuts and scrapes. Called it a day after those 4. Did the other 12 today in about 2 hours. The other 4 on the drivers side were still a pain due to hoses, lines, and close wrapped wire bundles. All 8 on the passenger side were super easy in comparison.

Changed the PCV valve and cabin air filter today too. Glad this is finally done.

Im sitting at 110k and need to do plugs. No issues but I want to stay ahead of it. I keep bouncing between NGK laser iridium and the ruthenium. I understand the differences however want to see if anyone here as bothered to pay the extra $ for the ruthenium plugs and if it's noticeably worth it?
