| Great plugs, I've had them in my 5.4 truck motor for over six months now, with the same results as you. |

So, how does that fare with the people who bought them at the auto store and brought back a couple of days later? Many of the complaints were about dropped cylinders that returned with reinstallation of the old dead plugs. Some Fords lost overdrive when the crappy plug tricked PCM into failure mode, OD came back as soon as proper plug put in. We practically couldn't give them away, even when they were on sale.
You realize that there is absolutely nothing different between those and an old school thick electrode plug out of the '60s right? They're not even platinum, which means they may be good for only 20,000 miles.
The exact same gimmick in the early '60s was called 'Fire Injectors', Dad fell for it and put them in his '64 426 Stage III Ramchargers 8 bbl. wedge motor. Drove 'em for a coupla days and pulled them out telling me they were garbage. Then proceeded to throw them out in the back field as far as he could. A common plug with any kind of gap gimmick is still a common plug. You got more potential erosion material on the ground electrode, unfortunately the center is still the same soft material and will erode like lightning since that's where the wear takes place. Platinum plugs will last 3 times longer.
I took a perfectly reliable mower that always starts within 2 pulls and put a cast off E3 (new) in it, surprise, wouldn't even start although I tried. Put other 3 year old plug back in and instant running. Meaning another problem, you cannot set different gaps with that plug. The mower, as do all mowers, needed a closer gap, the E3 did not allow for that even though it was a lawn mower plug specified for the engine.
Almost anytime you change plugs you should feel the difference even with oldschool ones, it is the newness of the plug, not the material or gimmick that makes the change. That change is also the difference in measured power claimed, you can see that power go up on a dyno with a simple stock plug changeout. Of course you WON'T see that fact on the beautiful airbrush artwork showing how that plug makes as much fire as an atomic weapon. Sheer ridiculousness right up there with Splitfire.
Sorry guys, I wouldn't put those things in my tricycle....................... |

If the Ford 5.4 is the one with the super long tip plug in it, then the E3.70 plug shown to be correct for it appears to be a 2 piece affair just like the garbage Motorcraft stock plug. Meaning you are asking for severe damage possibilities when the plug pulls out and leaves the bottom half inside motor. The puller kit to relieve that problem was like $100+ in cost IIRC, and may not work with E3 plugs meaning head must be pulled to fix a broken one. That plug design is one of Ford's worst ideas and has caused super amounts of grief among truck owners nationwide. The only reliable plug replacement is the Champion one piece ended one specifically designed to combat that problem and those plugs ran like $20 apiece at the auto store.
I base the conclusion on an E3.70 pictured on Amazon.com, it is pretty clearly a two piece end. |
