Has anyone DIY'd spark plug replacement?

[6of36]

Could have been. There are a lot on YouTube if you look for fake nkg. I did not know it was so prevalent until you brought it up though.

I just randomly ran across it, and it caught my eye. I wouldn't think they would go to the expense to counterfeit something as cheap as spark plugs, but I guess everything can be made for pennies on the dollar in China.

At $13-$15 a piece, plugs aren't so cheap anymore.

Work has me back on the road so I'm currently logging 156 miles a day with my commute. I'll run a couple more tanks before I comment on any other noticed improvements like mileage but I have noticed that the truck is idling so smooth again that at times it seems like it's not even running and I have to look down at the Tach.

My first 100k miles I had the dealer do it. They charged me $600.

I’m sitting at 212K miles now and decided to tackle this project myself because dealer now wants $1300.

NGK iridium from rock auto.

I have the etorque. It was a tight, but I’m a man and spit on that bracket and slid on through.

About a three hour job. That’s with three children insisting on helping. Time for a beer.

Those plugs are still good

Bought some Ernie Ball guitar strings off Amazon. Fakes. Sent Ernie Ball photos of the strings and they confirmed. Sent me 3 3 packs for free.
I don’t trust Amazon for anything.

On another note. At 81K am noticing a slight tremble. Time for fuel injector cleaner?

plugs are preventative maintenance replacing them was the right thing to do. the old one's are still good so put them in the tool box.

I'm at 114Kmiles and getting a slight bit of stumbling at idle. I know I'm a bit late on spark plug replacement so thinking that might help. Searched the subject, came up empty, so I'm curious if anyone has done this yet and how difficult it might be. I know the actual replacement job is straightforward, I'm more focused on the accessibility factor, especially to the rear-most plugs. Any help would be appreciated.

I used a 1/4 drive for the coil packs back by the break booster and the plugs socket 3/8 with small extension and spark plug socket it it not to bad once you get those out of the way , I have the Etorque so it was a slight pain to work around that.

Couple folks have said they’re still good. 112K miles on em. I’m no expert, what’s a “bad” plug look like? How many more miles you reckon I could have gone? I’m split 70/30 on highway vs city driving.

I appreciate your video. I didn’t remove the rebreather or oil fill foam. Also didn’t get the bracket wiggled as loose as you. Cut the zip tie holding down the girth working for injectors which gave me enough wiggle room to manipulate that triangle bracket. Only dropped my 1/4 inch drive ratchet once for the coil packs.

I did however manage to lose the rubber grommet inside spark plug socket. I had to switch from the famous magnetic Amazon spark plug socket to one I had in the tool box for the cylinder up against booster.

That took an extra half hour on this two with trial and error refeeding socket down to recover the rubber still attached to the new plug.

That was the only time I almost took the lords name in vain.

112k on it and those were the original plugs......that's a sign of a good running motor. really the best thing one can do is keep up with the recommended maintenance barring the transmission that has "lifetime fluid" -there is no such thing. the transmission should have a service/fluid change at around 60k no matter what mopar tells you. but youtube Justin Wheeler with the high mileage edition 2019 limited was at 250k last i saw and never serviced the trans.......i have nothing to prove so i'll just go ahead and get the service done. lol

I’m at 212K, no transmission service yet.

Currently on the fence. Some say it would do more harm than good at this point….

I have 2.5 years of Mopar Max care. If trans goes, hopefully it’s in 2.5 years.

Those plugs aren’t OG. Today’s change make third set. Factory were changed at 99.9 k miles. Second set replaced today at 212K

Nothing wrong with doing a drain and fill in your transmission. Just don't get it flushed. That's where the problems come from.

Generally, when the ground strap starts getting eaten back from the electrode, is when it's time to replace them. As long as the porcelain isn't cracked and the ground strap is intact, the plug is still good.
Strangely, on my previous truck (2003 hemi) I changed the plugs around 155K miles hoping to improve the fuel mileage; the ground strap was missing about 1/16th" yet the truck still idled silky smooth and drove fine. Fuel mileage didn't change one bit, I'm guessing the dual plug configuration on the hemi does have benefits other than emissions.

Left is a bad plug and similar to what mine looked like at 155K miles

These new platinum and iridium plugs are really good, they don't wear or fall off in performance like the old copper plugs do

Not on modern engines. Will it hurt, no but those plugs are fine

I'm at 96K with no trans service yet, I have the 7 year/unlimited mileage extended warranty so I'm not concerned with it; I plan on trading this truck just after the warranty is expired. My last truck went 275K on the original fluid and filter and ever skipped a beat
