05 Mustang GT 18384 miles, no tune, K&N CAI and Pypes axle backs.

Finally received Champion (#7989) from sparkplugs.com. The Champions are a one piece fine wire platinum and should last a very long time. Ask sparkplugs.com for 10% discount #.

I followed Fords TSB 08-1-9, cold motor (room temp) , but using PB-Blaster. Soak time of one hour.

Breaking the plugs loose was scary. I set my torque wench @35ft-lb and went for it.
They all broke loose with a loud pop. After one hour soak time, they all came out screeching, with little effort. All was good.

All of the old plugs had moderate carbon build up, but the PB-Blaster soften it greatly.

Installed Champions, using anti-seize as TSB.

I drove 50 mile with the Champions so far. I feel or hear no difference from OEM plugs

Its all good. . . .

 

Are those standard style plus gap wise.Like the old plugs or they the same we have now.

 

Standard plug style. I gapped @.044.

 

I might have too look into them.

 

Ford says to take them out when the motor is cold!?!?

 

No, read again. That was his only exception to the ford TSB. TSB says warm motor...

 

The latest TSB 08-1-9, states cold engine.
But to soak with carb cleaner.

 

I stand corrected.

 

ugh $19 a sparkplug is downright painful

 

Good info!

Good info but I am curious as to why not just stick with OEM plugs? I am thinking about replacing mine soon since I have 60,000km on the car but not sure if there is a huge benefit in going with different plugs.

 

Aluminum heads, ALWAYS COLD !!!!!!!!!!!!!!!

Steel plugs screwed into aluminum is asking for trouble.....................

 

Don't be too sorry. They DID specify doing this on a WARM engine at one point, mainly because carbon is more pliable at warmer temperatures.

The 3V heads suffer a problem where the 2-piece OEM plugs can be carbon-locked to the cylinder head causing it to break off while trying to remove them. The Champions are being touted as an OEM-spec 1-piece replacement. I am sure that we will see some better offerings in the future: 1-piece iridium plugs, etc...

I checked with our Aussie 3V owners and they did not report any issues. One guy had 160,000 km on his Falcon 5.4 3V and removed the stock plugs without any problems. It is possible they are using different spark plugs.

 

I have a 2004 F150 with the same style plugs and I broke one removing it as per the TSB. A one piece plug would be way better. I did get the broken part out of the head my making a copy of the tool used by Ford for this issue.

I have to do the other 6 plugs, just scared to, and the fact that the plugs are so **** expensive.

 

Because they are 2 piece and they are crap, they separate in the head when removed. Don't worry if your getting ready to change your plugs you'll know why soon enough

 

Just changed mine at 32000 mi. Sqeeking all the way. Warmed up the motor, loosened them about an 1/8 of a turn (felt like they were going to break off), soaked them with good old WD40 for about 5 hours, was a little scary, Ford needs a kick in the *** on that one.

 

can you post a picture of the tool you made please?

 

Not to high jack the thread but who makes 1 piece HT0 plugs for Supercharged engines? Thanks...

 

I don't get it. Whats the point of changing out your plugs unless your running nitrous, turbo or SC? I'll let the Ford guys dig out my spark plug nubs when they break 'em off. They are supposed to be good for 100k, unless your having trouble with them whats the bennifit?

Don't shoot me, just curious

 

I would think a big part of that is the fact that I don't believe spark plugs are actually covered under warranty, the other part being that if a Ford tech breaks them off, you will end up paying for it one way or another LOL.
