who on here uses them, how well do they work in the modular engines i got some free bosh 4 prong plugs and put them in and started my truck up and it ran like crap all the way to the parts store so i could buy new motorcraft ones,

are they worth the money and do they work well in the ford trucks

 

i was told by almost everyone on here with any experience that nothing runs as well as motorcrafts in our trucks..

i say this because I was also looking at the E3's before the guys on here saved me from buying them haha

 

lol thanks, thats what ive heard but i wasnt sure, i know a guy with a 2007 gmc 5.3 and he has e3 plugs and wires and said he picked up a little fuel milage because of the way they fire?? and i watch powerblock on spike and they always use e3 and that crappy purple motor oil

 

Actually, more than likely its not them, they just do some shots with the camera making it look like they do because they probably sponsor/endorse them..haha

So whenever hes pourin that royal purple into the funnel, it was probably filled with catrol earlier that day!! haha!

 

i have a buddy who has them in his chevy pickup. i didnt notice anything special about performance and he said fuel mileage hasnt really changed, not enough to really recommend the plugs anyways. i would just stick to motorcraft or denso.
