Best plugs for 5.4L

I want to change the spark plugs on my 2007 F150 5.4L. What are the best plugs to put in? E3's??

Just making sure: you do know about the issue of the plugs breaking in two and the extraction tool that you would need to do this job right? As for the replacement plugs, I have not read of too many using e3's on here. There is a champion plug that some have had success with. It's selling point is that it is a one piece plug that won't break on your next change, but some have complained of their truck not running as good on the champions, others say it is fine. Or or course you can just go back with motorcraft.

I put the Motorcraft plugs in mine. If you change them every 60-70k and have the Lisle tool then you shouldn't have to worry too much about the breaking.

Yes I have heard about them braking. I have 69,990 miles on this new to me truck. I started using injector cleaner on the last tank and I will use more this fill up.
So just get Motocrafts? are the one piece now?
Is this the right tool?

yes that is the tool. I think the motorcraft are still two piece but I'm not sure. I think I remember reading that the champions are the only one piece you can get

The motorcrafts are still two piece. I just don't leave them in for the full 100K that manufacture recommends. Yes, that Lisle tool is a must for any 2004-2008 F150 owner.

Thanks, I will order the tool. I have never been a fan of champions but I do not like the idea of the two piece plug. I looked at the E3's and they are one piece, I just do not know how they would run in the truck.
Is 10-11 MPG normal for local short hilly driving with this 5.4L truck?? I just did my first fill up since I picked up the truck with a full tank and it is about 10 give or take MPG. I hope it will not stay like this!!!!

I changed mine out at 70K and after much research ended up going with the motorcraft plugs. Found mine at a great price and just could not justify the extra cost for other makes when they are similar too the motorcraft or have a copper electrode instead of a platinum electrode.

Later build 2007 5.4's should have factory installed 1 piece plugs.

Yeah new designed heads with different plugs. I believe they have brown boots on the coils instead of black.

It's after November of 2007. I don't know if any of them with the new head design would even be 07 models, they should all be 08's.

If you do decide to run the E3's keep us all updated on their performance. I for one am quite curious as I do not know anyone who has run them in the 5.4 3 valve. I have had decent luck with them in my lawnmower and weed eater though.
