I'm in the same boat as Broncoholic; 1999 V-10, and right at 98,000 miles. The dealership wants $460 just to R&R the plugs. I'm looking at it as (+/-) $32 for plugs, $80 for a Craftsman/Microtork torque wrench, and $80 for boots.

I'm just a tad apprehensive from the horror stories I've read about popping the threads. If I'm reading things correctly, as long as I use the torque wrench and stick to 132 in/lb I'll be ok. In other words, the issue of popping threads is due to plugs coming loose while driving the truck and nobody has stripped out the heads while torquing down the plugs properly.

Am I correct?

Yep that is what I was told when hunting up plugs. The SP479 is a Motorcraft part #, the AGSF22WM is a Ford part number.

Actually that would be 168 in/lb or 14 ft/lb.

I have never heard of the plugs getting stripped while installing them with the proper torque. Usually if the threads strip...it will be when uninstalling.

That is good to know, I use the copper antisieze is this the best for steel to aluminum. I am a cast Iron head guy.

I am apprehensive about the change, I might let them soak in Kroil for a week

Not trying to start something here, but form what I've read - including the original post - the stated torque measurement is 132 in/lbs (11 ft/lbs). so if you are saying that this is incorrect, please name your source and let's get to the bottom of this.

Thanks

Several threads here in the forum...but here are just a few that indicate 168 in/lbs.

Ok...so there they are. If you want to search...just enter 168 and there they are.

And those same threads also indicate from as low as 84 in-lbs (7 ft/lbs) all the way up to 25 and 30 ft/lbs.

Doesn't seem like anyone agrees on this subject.

From Autolite's website: http://www.autolite.com/pdf/TorqueSpecs.pdf

From NGK's website: http://www.ngksparkplugs.com/techinf...stallation.asp


These plugs are 14mm thread Conical seat type (without gasket). Note the recommended torque is 7-15 lb-ft for aluminum heads. Autolite's specs state:
NOTE: Spark plugs should be installed with clean and dry threads to avoid overtorquing or stretching the spark plug which can, and often does, result in engine damage.
I used anti-seize because I don't think it will significantly affect the torque but will protect the threads from corrosion and galling when it is time to replace these plugs.

A plug replacement for '03 F250 that went well

I recently bought a 2003 F250 Triton 5.4. I decided it would be wise to take my chances with plug replacement now (at 76,449 miles) , rather than live with the threat of a much more expensive problem down the road.

I guess I was lucky. All eight plugs came out without breaking, although one looked like it might've been about to seize. Another was rusted, because there was water sitting in the plug well. The rubber boot on that wet plug showed rust stains on the outside, but there was no evidence that water had gotten to the connection between the coil pack and the plug.

The last plug change I did was last summer on my old plow truck, a '78 Bronco 400 cu.in. That was comparatively easy, with no fuel rails, COPs, or other stuff in the way, so I had this one done by an experienced mechanic at the local shop. He was able to do it in a couple of hours (including a short break), without removing the fuel rails. It the money I paid was dirt cheap for the peace of mind alone. The new plugs, and whatever enhanced performance and/or mileage they might bring are just a bonus.

<A href="http://www.sanders-indev.com/F250/FactoryPlugsF25076449mi.jpeg">Here is a picture</A>
of the removed original-equipment plugs, and the packaging from the replacement plugs.

Well I have 170,000 miles my last plug change was at 106,000 miles.

I had my first plug blowout. Went camping in Galveston Tx this weekend. About a 60 mile trip from home.

We went into town from the State Park. Did some shopping at walmart. When I started the engine BANG sounded like it threw a rod. It was a plug blowing out.

It broke the hold down tab on the COP.

Called a tow service but before they came I tried to reinstall the plug. Got one turn on it before it tightened up. Started the engine and to my surprise the plug stayed in.

I canceled the TOW and returned to the State Park. The next day I drove 60 miles home. Today I decided to check it out before I got back on the road.

Pulled the plug. Threads looked good as far as I can see. The plug looked brand new. The anti-seize is still evident on the threads.

I decided to torque the plug to specs. The one thread gave away at about 5ft lb.

To the shop to have an insert installed. Anyone have experience with that?

Second plug change. 196,000 miles

Did my second Plug change this weekend.

Eight years, 90,000 miles and one plug blowout later. 196,000 miles on this thing.

I am getting ready for a 5,000 miles to Colorado over the Continental divide in this 11 year old truck. So a plug change is on order.

The plugs look pretty good. One bank plugs 1-5 look to be running a tad richer than the other. Some minor deposits on the plugs on that side.

The gap has opened slightly on a couple. Still within tolerances.

The plug in the cylinder with the time-sert looks just like the other nine. Bore scoped all the threads. It is difficult to identify the cylinder with the time-sert. Looks the same as the others.

Changed the air filter. Went back to a Motorcraft filter. Mileage jumped to 16 mpg on highway from 12.9. The Motorcraft filter breaths better than the *&&^% Fram I was running.

About ready to go. Need to rotate tires, inspect brakes and I will be done.
