But
If you have a 2008 5.4 3v its more than likely that you have the redesigned heads that don't take the plugs that have the heat shield.
Just sayin ya know..........
Edit
If you have the brown cop boots then you can't use the e3.70

Good/bad reports, - out there, but vary. To be completely fair about the E3 - it has yet to be determined (it's a newer part).
The info above will help in your search. For your particular engine, use plug name and you can further your search, for your own determinations.
Take Care.

Most places have Motorcrafts' OEM replacement | SP-515 | for around $12.99 (MSRP, aka cost at most dealerships, is $25.89). I've seen them range from $10-$20. A set of plugs alone at $104 is expensive to me if you consider the cost of "normal" spark plugs! That being said, SP-515 are double platinum (I've generally seen considered the "direct" OEM replacement), but you can get SP-507 (regular platinum) for less.
Something to remember is the 5.4L 3V is very "special" and takes a unique plug that not many companies want to spend development resources on for only 1 engine. That's why they cost more than a typical "off-the-shelf" plug that can be used on a range of engines.
For reference, here's a JEGS pricing comparison:
- E3.70 : $5.99 ea
- Motorcraft SP-515 : $16.99 ea
- Motorcraft SP-507 : $7.99 ea
I'm preparing to do my change at 78k in my 05 5.4 since I have a nasty misfire under "hard" acceleration (on-ramps, etc.). I'm waiting for my tank with seafoam to run out, then I'll start the long process of PB Blasting, waiting 2 hours, PB Blasting, waiting 2 hours, repeat. Now I'm just trying to decide whether to get the E3.70 or SP-515.
