Has anybody tried either of these in their trucks yet? Oh yeah, there for a 2007.

To the OP, I have been running the E3.70's in my 07 Navi for the last year. I have better throttle response and acceleration compared to the stock plugs. only a slight improvement in economy. I changed to the E3.70's for one reason and that was to ease changing the plugs next (solid one piece construction), plus I got them off of amazon for less than the Motorcraft. I was lucky and non broke when I changed them out in January.
However, I will say that when towing my 28' TT over a 7-8% grade the motor responded very well to the increased burn properties of the E3's. I was able to go over the hill at 40 mph and only broke 2500 rpm once with 6900 lbs. in tow and the whole Fam Damily loaded up too. I think it was near 13K GCWR. BTW, the local stealership recommended the two piece plugs as replacement.
