TENSION

Changed mine with 130,000 on the odometer, used a 3/8 impact, warm motor, with a shot of "blaster" in the chase. When they break, the lisle tool is the best to use for removing the broken tip. I've changed over 100 of them, with about a 60/40 ratio of not breaking/breaking. Champion makes a great replacement for the original ford crap.

If its a 2v 4.6l they do not break. 3v 4.6l they do. Sorry about that.

Another way I have good luck with but it is time consuming is attempt to loosen the spark plug. As soon as you feel it come loose, tighten it. Then work it back and forth until you hear it start to pop, thats a good thing. If its popping when coming out then keep loosing it. It will come out. But go slow. If the impact method and this method doesn't work, they where breaking regardless.

2008 was the last year of these. Your ok.

It looks like they didnt put the 3 valve 4.6 in the F150 till 2009. It has regular valve covers and the 5.4 has valve covers with a hump.

Here is a picture of mine, I will probably pull one off to see if this is a 3 valve but I assume it is 2 valve with regular plugs and standard looking valve covers.

Can anyone offer some insight before I dig in:
1. It has normal plugs right?
2. Its 2 valve(see valve covers)?

Thats a 2v. You should be fine. Hand start all and thread in by hand.

Does this also apply to my '03 V10? I've heard stories of plug issues with my motor but the dealer bulletin link didn't list mine.

03 v10's are 2v also. The issue with 2v's is they can blow the spark plugs out. Most of the time its from the plugs not being torqued tight enough or cross threaded. Don't be afraid to tighten them up. They need to seat good into the head or exhaust gas will seep by and eventually they will blow out. Replace the boots on them as well.

Keith, remove coil bolt 7mm,,,lift coil up you will see a spring that goes to the spark plug ,pull that out,,now take a screw small tip and run it down between the spark plug and spark plug boot,,work the screwdriver all around the bottom of the boot ,,,you want to loosen the boot away from the spark plug before you try to pullthe rubber boot out,,i will even split the boot near the bottom of it,with the screwdriver,,, or you can use a straight long seal pick works well also,,,,to split the boot near the bottom,,,I have had a harder time removing those boots than the spark plugs,,,here my point,,,if you don't loosen the boot from the spark,,,when you go to pull it up,,the boot will rip in half,,and you will have a hell of a time just getting the boot out,,,it is like a sparkplug in a hemi head,,the spark plug sits down a hole about 5in,s,,,use a 5/8 spark plug socket,,,also use a 7in piece of fuel line hose,,,to remove and install the plugs from the head,,,works great,,,been doing those type plugs since 2003
