Autolite has been manufacturing spark plugs since 1936 and are your go-to industry standard. The Autolite Iridium range are manufactured with an iridium-enhanced centre electrode, designed to eliminate gap erosion and provide more focused ignition and impressive durability. A copper glass seal bonds the ceramic insulator and centre post together ensuring strong spark and a 100% leak proof seal.
Coupled with a cold formed steel shell and precision rolled threads, Autolite spark plugs exhibit great durability and anti-seize properties.
