Autolite Spark Plugs 8 pc Double Platinum sku-1178392697

This 8 pc set of Autolite Spark Plugs, sku-1178392697 (UPC 461178392692), contains double platinum plugs listed for Ford F-250 V8 engines from 1973-1996 in 5.0L, 5.8L, 6.6L and 7.5L sizes. Platinum on both electrodes reduces gap erosion and misfires in distributorless ignition systems, which fire in both directions. A yttrium-enhanced ground electrode transfers heat.

The plugs have a 5-year guarantee. Autolite makes plugs for foreign and domestic vehicles, including iridium, platinum, double platinum and small-engine types; its stated design goals include durability, ignitability, fuel efficiency and meeting modern engine and emissions requirements.

Founded in 1911 as a buggy-lamp manufacturer, Autolite began making spark plugs in the 1930s and had made over 10 billion by 2007.
