Stick with OEM

i put the e3's in after 140K on the stock ones, although that was only last week i can already tell by my trip meter the mileage has gone up, not much. But it has gone up... I feel like almost anything is better than the stock ones in there so i went for it.

Put those in my wifes old jeep and 2 electrodes melted off. But i put some in my sisters mustang with a 4.6 and it ran a lot better and they have been on for 25k.

However with our trucks i would stick with motorcraft or autolite because all those weird little issues.

Also check gap. Mine ran like poo then i gapped them all and it runs great.

My buddy put some E3s in his 05 a few months ago. Truck ran great but they went bad already. Just stick with oem.

Can't add anything as far as the truck - but I use these in my Harley and love 'em.

There was a long thread on these quite a while back. I'm not even sure it was on this forum. (it's an age thing) Someone did a test and loved them for about 5000 miles and then they went to crap and he ended up pulling them out.

I love them in my snowblower, but when the time comes I think I'll stick with OEM in my truck.

Alot that I have read is that people either love them or hate them. I have used E3 in all my outdoor equipment and have absolutely loved them. They never go out. But in other auto forums I hear they either work great or they dont last long. I do not know if these people are gapping them correctly though. I was alwasy going to try a set but with the price of them I think I will go with the motorcraft iridium. Alot of the 5.4 drivers say go with Brisk due to the problems the 5.4 has with spark plugs

I read up on these some time back....they were originally designed for small displacement engines such as lawn mowers, snowmobiles, and others on this line, as they are more likely to create polutants that have been exempt from the current laws of automobiles. For these small engines, they work great, but it has been a hit or miss with engines used in automobiles. From other forum posts, it's had decent success with 4 and some 6 cylinder engines; those with 8 cylinders and above have had minimal success with them.

I'd stay with stock or perhaps a platinum type plug.
