Finally changed the spark plugs after 98K miles. Decided not to tackle the job myself
. I had the service company install Champion 570 factory plug equivalents. The good news
is my idle is very smooth now, as it was when the A/C was on. The idle has jump from 500 to 600. I can barely tell the engine is running. Check out the picks I attached of the old spark plugs. Other than some gap differences, a little metal erosion and a little carbon, I thought
the plugs looked pretty good for 98K miles. I don't recommend
that you wait as long as I did to change your plugs. Many have told me of the dangers of leaving plugs in to long in aluminum heads. And many have told me about Ford Mustang plug problems with leaving them in for 100K and the aluminum threads come out with the plugs. I will say though, I was very lucky as these threads look pretty good.
On a side story, I called around a got 3 prices to change the plugs because I couldn't bring myself to do the job
. The lowest price I got was $125 from Pep Boys so I went there. What a joke, after they started the job and I've walked over to a near by Home Depot to do some window shopping
, they call me and say they can't complete the work. They under estimated the job and the new price is now $330
. The mechanic said my truck was different than other Dodge trucks with a Hemi and he was going to have to remove the brake booster, what an idiot
. I told him that he must have just started in this line of work and put my truck back together. I took my truck to Firestone Service Center which was now the lowest price. They completed the job in about 2 hours for $230 plus tax. This is eating into my mod budget
. But I'm glad this is done and over with until the next 30K.
