Has anyone tried the new E3 square fire spark plugs? If so, what do you think of them?

 

No personal experience, however I have always been told that dodges like standard plugs over exotics. I assume that is probably why we have the recommended 30K change over your standard 100K platinum changes. Sounds like youre gettn some snow.

i went from the standard champions to the autolit 5244 platinums and it was a mistake. i lost 45/50 miles to a tank of gas. was getting 370/380 to 22 gallons and that dropped to 330 if i was lucky. switched back to the regular champions and my mileage shot back up. i have a 05 4.7. was running a 97 5.2 and ran nothing but champions. truck ran like a champ the day i traded it in for my 05
