Description

The Autolite Spark Plug AUT25 is engineered to deliver quick starts, good fuel efficiency, and smooth acceleration. Its copper core center electrode aids in thermal control and improves resistance to fouling. The high alumina multi-rib ceramic insulator provides thermal conductivity and superior insulation for increased strength. Designed with a nickel-plated shell that is corrosion-resistant, it offers increased durability for extended periods. This spark plug is an ideal replacement for older vehicles that originally used copper spark plugs, fitting 99% of such vehicles. It matches fit, form, and function for both foreign and domestic vehicles, guaranteeing performance for 2 years.
