hi, i have a 2008 f150 5.4 , i have been warned not to tackle the spark plugs myself, but this site mentions an updated design on engine build dates 11/30/07 , does that mean that my 2008 automatically have the updated plugs? or is there older engines in 2008 trucks? how to be sure,someone mentioned brown coils indicating the newer version,thanks for helping

Yep. Brown coils and an engine date after 10/07. You can do it yourself. Rent the Lisle tool. Run a few cans of seafoam. Then tackel it.

I forget the months, but I'm sure it switched part way thru 2008 model year, if it was 11/30/07 and your truck was built after that, you should be good...Your born on date is on the inside of your door...when I grabbed spark plugs for mine they asked me the month it was built, which was 06/08, and said it takes regular plugs...also my coil boots were brown...did plugs and coils myself a couple hundred miles ago and all seems well (with that part of the truck anyway)…

It can be done yourself either way...I believe on the older heads they redesigned the spark plug itself into a single piece so no more breaking...however if they are the original ones, or older 2 or 3 piece plugs, then it may get complicated...I found #5 and #6 very simple to remove if you want to check and see what you got going on...or just check your build date and ask a competent clerk at the parts store...

If it takes the regular ones, I wouldn't say it's simple, but definitely doable and cheaper...I've heard of people having to pay $500+ just for plug change at a dealership...it was worth the swearing and scratches on my arms to save the money, especially for a sp change...

hey thanks for the reply, but why do i need the seafoam and lisle tool if mine is the new updated one piece version?

O'reilly auto parts allows you to rent the spark plug tool to save a few bucks but then I'd reccomend using the OTC tool for the plugs. It's just a deep well socket but I think it helps.
