... well, the dealer did, and no problemo. All came out without an issue and they're in great shape (53,000 km's). Just thought I'd let everyone know the good news

I also had the thrird brake light replaced as per the TSB as well as the tube/elbow installed incase I get a leak on the floor on the passenger side.
Oh, I figured it was time to have the tranny serviced as well.

Cost? Just the price of the tranny service (about 100 bux).

 

That's good news on the plugs! What is that, about 40,000 miles? Mine were changed successfully by the dealer at 65,000.

 

53,000 km's is exactly 32,934 miles.

The dealer I go to has yet to have a problem with any plugs breaking.

BTW, as far as the tranny service goes, they told me that they don't change the filter anymore. They only do a flush, which was what I wanted anyway.

 

I had the tranny flushed on mine as well, at the 65,500 miles. Had the filter changed at 30,000. My dealer said they had only one plug break so far and it was on a truck with 95,000 that idled all day. An oil field service truck.

They said that my plugs would have gone a lot longer, but I was just happy to get it over with, stop the concern. The tips on the plugs removed looked almost new. Hard to believe they had that many miles on them.

 

Good news on the plugs . It must be a crap shoot if they break or not, some at higher mileages don't break and some with only 30k+ miles like mine break go figure.

 

Crapshoot, nice line.

Great news on the plugs last50.

 

It is peculiar how some break at low mileage, & others at are fine at high mileage........it's a total crap shoot!............

 

did the plug issue affect the 4.6?

 

Noticed any performance gains with the new plugs?

 

The dealer I go to is a fairly high volume dealer. As per that other thread mentioning Ford quality being at par with Honduh and Yota; well the service manager was telling me that warranty work has gone way down in the last few years.

 

No, only the 4.6s with 3Vs.

 

Nope; she runs just as good now as when I brought it in. No difference in smoothness at idle either. It was smooth before, and it's just as smooth now. The old plugs were fine and could have gone for another 50 k km's easily, I'm sure.

 

Upon looking at your truck in your gallery, you have the same Billet Aluminum grill, sill plate protectors, & factory bed liner as me!.......Spooky!.......

 

So they changed out your plugs for free?

 

I didn't notice any difference in the way mine ran either. It has always ran great.
