Thread: e3 plugs

Never heard of them. Spark Plugs | Automotive Spark Plug | Motorcycle Spark Plugs | E3 Spark Plugs Taking a look...


okay, these look like they're based on side-gapped plugs... but from the factory. Doesn't list any kind of metals... Seems like a good idea at first... When I think about it, I've seen a couple photos of these plugs smashed by detonation, I think. Can't recall where, or how many, though.

I guess they would be fine if you could figure out heat ranges with them... which I'm too dumb to do.

use auto lite plugs my car loves em

Exactly.

Autolite's...or NGK's...and if your stock? AC Delco's. Live with it...E3 plugs are a waste of money.

I have used e3's in my GTP, and they worked, but I did get a bit more KR out of them, so I switched back to Autolite's.

Customer put them in his Chevy pickup, developed a misfire, changed back to AC's and no more misfire. That's the only experience i have with them.
