Spark Plugs and Gen III Hemis

Stock 5.7 Hemi in a 2012 Charger R/T - plugs need to be changed...I was looking at the E3 plugs as well as the Iridium offerings and thought I would ask before I bought them...thanks

Don't put E3 plugs in anything you rely on. Been there, done that.

I had a dead misfire within 500 miles of installation, 250 miles from home. Swapped the plugs out for OEM replacements in an AutoZone parking lot and got a full refund on the E3s. JUNK.

The experience continues to drive home my theory of "If OEMs aren't doing it, nether should you". [to a certain extent]. If this magical spark plug theory was so great, offered more power and better fuel economy...I'm absolutely sure the OEMs chasing those deliverables would be using that technology.

Buy the factory NGK's. Nothing better is out there.

The truth. You can spend more and get far less.
