Is there anyone using E3 spark plugs?

If so, what do you think?

Waste of money.

Friends I read so much in this post, I dizzy
I went to buy the spark plugs for my ZR1 1992 and they sold me AC DELCO 41-950 (see picture). Are they correct? Specifically, if it is not, someone can tell me which one do you recommend.

May be Hib …:-)

Thanks in advance!

A typical advertising scam. They convince gullible people that an easy swap will make extra HP. Just like back in the 80’s when the first mod every Chevy guy did was Roller Rockers.

Are AC Delco 41950 the OEM? I don't know, that is my doubt.

AC Delco 41-110 iridium I believe are OEM. That's what I used in my 09.

Opps just noticed your looking for a 92.

Trash. The only brand of plugs that I use besides OEM AC-Delco plugs are NGK's.

like stated in prior posts, the E3 spark plug is pure marketing, any vehicle that needs plugs will run better with new plugs and make more power than before the plug change. new plugs v new plugs there will be no difference in performance, or any other parameter that can be measured, except the gullibility quotient.

I love E3 spark plugs in my lawn equipment, mower, weed wacker, blower, etc. E3 provides absolutely NO data for use in LS engines, AC Delco in mine.

I was a member of the Camaro5 forum for seven years until I sold/traded my '011 SS LS3 Camaro for a 2006 LS2 A6 last August. While on the Camaro forum I read many posts of owners swapping in E3's and having running issues with the spark from those plugs. Stock OEM plugs and wires will make your computer happy.
