Anyone out there with a 4.6 had their plugs changed at the dealership or garage and be willing to say what they paid. Im thinking of taking mine in for plugs, im just reaching 100,000 miles on mine, and im to lazy to do it. Thanks!

 

Anyone have this done on a 4.6?

 

I'm at 91000 on my 04 4.6 and I was wondering the same thing.

How much do we have to save up to have this done?

 

Last year I had the spark plugs changed on my 2004 4.6 for $100.00. The spark plugs were $34.72 and labor was the rest of the cost. This was done at a local shop. The mileage on the truck at the time was 82,274.

 

i have not done them yet, but i have read here that the 4.6 doesn't have the problems the 5.4 does

 

Ya I know the 4.6 doesn't have the spark plug problem. That's why I was wondering what people paid for them. Cause I know what the for the 5.4 can be

 

Why does the 4.6 not have this problem? I have an 05, and about 75,000.

 

I checked with a local dealership here in Kansas City. To change the plug they want $260. The tech that does this work recomended cleaning the fuel injection system to clean out the carbon fron the cylinders before changing the plug at a cost of $140. He also told me that if any of the plug broke off while doing the job it would cost $50 per plug. We also talked about the TSB that is out on that and he said that with the fuel system cleaning he has not had a plug break yet. I think I will let them do it this time, instead of me screwing something up.

 

I have heard some do and some don't. I had an 04 F150 with 138,000 on it when the plug were changed in it.

 

I changed the plugs myself. Had no problems. My dealer quoted me $300.

 

Same here... ~$300 unless they broke a plug and then the overtime is on me. I thought that was a little unfair as the shop should take some responsibility in proper procedure. I feel that's what I'd be paying for by taking it to the shop... peace of mind that if they break something while it's there, they cover it.

I'm going to just do it myself. If I break a plug, then I'll deal with that later.

 

The spark plug in a 4.6l has a one piece base and I have never seen one break off yet. They are more common to lose their torque and blow out.

 

My cousin has a F-150 with a 4.6 as a company vehicle. He keeps them 3 years and they have about 215,000-225,000 miles on them. He has never changed a plug and has never had a problem. He drives 70,000-75,000 miles per year.

 

As I looked at my 08, seems as if the fuel rails have to come off to change the plugs. Nice :/

 

These quotes for $260 and $300 with extra cost for broken plugs are what is charged for a plug change on a 5.4 with all its problems. The price for a 4.6, which doesn't have the same issues, should be less.
