Being a 2008, you should have the redesigned heads, since they started in late '07. Even still, I'd take the TSB Method of doing your plugs because you're not really deviating too much from a standard plug change. Break them loose (1/8th of a turn), spray some carb cleaner down in the wells and let it soak overnight, replace plugs and then put anti-seize on the electrode sleeve.

Only if the ENGINE was built after 10/07, not the truck

Hootsworth

You are correct and you make a good point. I assumed being an '08, you'd get an engine around that period, but upon thinking, Ford is a company like anyone else. If they've got engines sitting in a warehouse, why not use it?

You know what they say assuming things..

Was looking at two 08 trucks when I bought mine a few weeks ago. 1 has an engine build date of 9/07, and the one I got was 5/08. Some of the earlier 08's still had the older engine /head style. That's one of the big reasons I chose the one I did.

Remember early 08's hit the lots in Sept 07 before the redesigned heads were configured.

Are you sure you're checking the plug BOOT and not just the coil on plug? If yours is the redesigned head, it should look like this.

yep...

thanks! I was looking at the COP not the actual boot (I assume you have to pull the cop/boot off to actually see the color of the boot?) The engine was manufactured in May of 08, so they are surely brown. Thanks for all the help guys

Yup, you need to look at the actual boot If the engine was made in May of 08, then youre fine. Easy spark plug change. Have fun!

Aren't the coil's the same on a 04-07 vs . the 08?

I thought the 08's just use brown boots no ?
