E3 Spark Plugs

[Black Thunder 715]

Has anybody installed E3 spark plugs in a stock engine? American Muscle web site sells them (Part # E3.53). Does anybody have an honest opinion? Thank you for any response.

Don't waste your money, Brisk GR12YS plugs, NGK BR7EF or TR7IX plugs are the best plugs for our cars.

+1 on skipping E3 plugs, in favor of NGKs. No first-hand experience with Brisk but, FWIW, did NOT hear good things from a local guy who tried them in his Shelby.

Lund recommended Brisk over NGKs, so far them seem ok, I still might go back to the BR7EF plugs

VMP pushes them too but, like I said, a local guy (with a VMP tune) was really unhappy with their performance. He ended up returning them and going back to NGKs.

My car didn’t like the BR7EF plugs. I tried them when I was trying to figure out some false knock issues on my car and the car would become jerky at a constant rpm. Fine at WOT. Went back to TR7IX and issues solved. Went with recommended gap on both plugs, not sure why I had issues with the plugs.

Edit, the plugs I tried were the BR7EF.

E3 and Brisk are garbage plugs, NGK are far better... the only reason vendors such as Lund and VMP push Brisk is for profit.

Do you run the Tr7ix plugs or the Br7ef plugs? I have usually only ran the BR7EF plugs

At my (local) tuner's recommendation, I went with TR7-IX plugs. Zero problems in two years since install and tune.

I also run the BR7EF , not a fan of IX plugs and I change them every year anyway so its a waste IMO

I know BR7EF plug is a little colder than the tr7, but I think the tr7 has better driveability.

I stayed with the Stock plugs for the 13-14, which from what i understand, was a slightly colder plug then previous years.
New was a very good price, Gapped at .030., but I am at stock boost levels.

No they are both the same heat range (7) hence the 7 in both part numbers, the only difference is the center electrode material in which I personally prefer nickel over iridium as iridium is meant to last longer but nickel burns better. Now a nickel electrode will run very slightly colder then the same heat range iridium electrode but its not significantly like a colder heat range plug itself and only aids in performance. Spec info from NGK site for each is below if your curious
