HEMI Spark Plug Change....What an easy job! :D

[Northern300c]

Just changed all 16 plugs and it was the easiest job in the world to do. Just make sure you blow out the area around the coil and the tubes before removing the old plugs.

I used Antiseize and torqued them to 15 ft lbs which is not very much at all. I think the old plugs were in there a lot more than that but could be just because they were in there for a while and a little seized in and dry. They squeaked when they were removed.

But again I state, what an easy job to do. Plugs cost me CDN$30 on sale. Took me longer to pull the 6 plugs out of my Blazer than it took to do all 16 on this HEMI. I love this car.

I also removed, cleaned and reinstalled the PCV valve and cleaned the throttle body.

The throttle body was a MESS, the front is fine, but the back had a layer of crud on it that was easily removed with throttle body cleaner, a toothbrush and a rag. About 2 minutes and it was clean as a whistle.

I just can't believe how easy this car is to work on.

I forgot to replug in the IAT sensor on the intake and I got a check engine light. Pulling the #11 fsue for two minutes removed that.

Do I have to relearn the windows, Stability control and the MDS when i remove the #11 fuse?

You shouldn't have to relearn. I have only had to relearn after disconnecting the battery.

How many miles are on the car and what was the condition of the plugs you removed?

Great question!

385000 miles

The plugs were not that bad at all. Most of them were 0.048 - 0.050 and a couple were 0.052. On plug had oil on the threads from a light seep from the plug tube seals but from the looks of the oil it has been there for a long time and there was very very little oil on the top portion of the threads.

Not bad at all really. The idle sure has smoothed out.

Man, that throttle body needs to be cleaned at least every 20,000miles.

Do you have any kind of aftermarket or modified intake or is it just the stock set-up?

Bone stock.

Don't believe the notion that it is the CAI gumming up the TB. It is the PCV vapor causing it. The front of the butterfly was clean as a whistle, it was the back that was the problem.

what kind of plugs do u use?? stock from Chrysler, or upgraded from an auto store?? and what is the socket size, im changing my plugs this week.

Changed my plugs about a month ago. It was so easy a caveman can do it. lol. I replaced mine with bosch platinum 4's. Nice plug. 4 times the spark. Only thing is that the plug is 6 bucks a pop, but well worth it.

Champion Standard Copper Core Plugs from an auto parts store, don't buy them from the dealer.

Socket is a standard size spark plug socket with the rubber insert.
