Product Description
Product Description 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.

Customer Reviews
The moment I changed to these plugs for my truck I noticed a slight increase in power and a general smoothness in the motor idling. I can't say my gas mileage was greatly improved but it did help some. Maybe 1-2 more mpg. Of course, during winter here in New England there wasn't much difference in mpg but take-off made a big difference. I don't do much highway driving but the few times I did it seemed to use somewhat less fuel, by my calculations. I like them enough that I bought a set for my antique sports car and two of my gas powered yard tools.Love these plugs, but they are hard to find for certain models.I've bought thes kind before and they last well they were in car almost 6 yrs I wish they would work in my Chrysler 300 thanksSon buenas.Put 4 of these in my Escort wagon and I can't keep it on the road!Had to add 400 HP!Tesla must have thought up these bad boys!love itOne of the best plugs I have used in many years. Iam going to order a set for my wife's Camry today. They are great.
