Ford upgrades spark plugs more often than they do underwear and any other part. If you really want to see a pissed off parts guy, throw him some random spark plug numbers and see how many times they upgrade.

 

So which spark plug number is the latest part???

 

Apparently the PZT2FF4s. I'll do some more checking around tomorrow.

 

Got my baby May 26 2005, I already hit 18,000 miles as of today.Should I get them changed know or wait a little longer,I don't want to run into problems.
I drive like a mad man....I love this truck!


Great job !Quintin!

 

Quintin, you better hurry before they change again....

But really, thanks for all your input. You've been more help than you can imagine.

 

These plugs will outlast the truck. Your wasting your time and money replacing them. It's a gimick. As I've stated earlier my last truck had the original plugs in it and it had over 200,000 miles and the engine ran real strong with no missing or hesitation.

I did ask about the mileage, but tech didn't remember/recall. As far as part #'s being different. I asked parts guy aobut that, he said it likely vendor change or/and production period. If it was updated plugs, he said it would be noted in his system but didn't see any. He said Ford will go through few # changes on those plugs through its life cycle.

 

I did a web search on (tips on how to replace / change spark plugs) and every article said, let the engine cool completely before changing the plugs, and especially if the heads are aluminum.

All spark plugs should be removed and checked every 30,000 miles - even if your car is "low maintenance" - you're told to change spark plugs at 100,000 miles. This prevents the plugs from seizing in the block, causing expensive repairs down the road.

I'm getting ready for the BIG day

 

I know that's what I was told years ago...when changing plugs, besure that the engine is completely cool down.

 

That is because they did not want you burning your widdle hands.

 

I would imagine repairing a broke plug or two would be cheaper than new heads, at least I hope it would be.


This sentence scares me a little. I think I am going to just keep them in until I sell the truck with 200K on it.

 

GIMICK? What year was your last truck?

 

For the life of me I can't figure out why you guys are changing plugs with so few miles on your trucks. The first recommended change in the manual is 100,000 miles.

I changed them in my '97 at 60k "just knowing it needed plugs" and the things looked brand new. Put another set in at 120k just because I had a fluid leak that filled one of the plug wells and those looked brand new as well. Truck didn't run any better after the changes either.

If they'll break with so few miles on one anyway.. why the heck test your luck? Run the things until you have to change them and hopefully by then they've come up with a fix for the problem. I'm seeing a bunch of people just jumping at the chance to have their heads pulled for no good reason.

 

I agree 110%

 

An employee of a nearby dealership told me there is going to be campaign on these spark plugs soon.
