Copper Core Spark Plugs deliver quick starts, improved fuel economy, and smooth acceleration. The copper-glass seal bonded insulator, terminal post, and center electrode ensure a tight seal that is 100 percent leak-proof, and the full copper core electrode improves heat transfer and optimizes plug life. Copper Core Spark Plugs feature high alumina ceramic for high dielectric strength, and a steel shell for installation robustness. The multi-rib insulator reduces the danger of flash over to prevent misfires, and the copper core center electrode provides higher thermal conductivity. These spark plugs are engineered with a high nickel alloy center and ground electrode for extended life. Autolite has over 100 years of engineering experience and has sold over 11 billion plugs. Since its inception, the Autolite brand has provided the automotive aftermarket and Original Equipment manufacturers the highest quality ignition products. Designed and engineered in the USA.
I was excited to try these E3 spark plugs, but two of them arrived damaged. I had to make a return, which was a hassle. The ones I ended up using seem to work fine, but the experience was frustrating overall.

Perfect for my Chevy
Just replaced the spark plugs in my Chevy Malibu with these E3 ones, and the difference is awesome! The car starts better and idles smoother. Great quality and a nice price for a pack of 4!

Solid replacements, but tricky to install
These E3 spark plugs work well for my Ford Focus, but I had a bit of a hard time getting them in. The performance is great once they're in, though! Just be prepared for some fussing around, especially if you’re not a pro at this stuff.
