Autolite Double Platinum Spark Plugs sku-3505944438

This 8 pc set of Autolite Double Platinum Spark Plugs, sku-3505944438, UPC 463505944437, is listed as compatible with the Ford F-150 5.4L V8 from 1997-2003. These Autolite Spark Plugs use a platinum-to-platinum design intended to reduce gap erosion and misfires and improve durability in distributorless ignition systems, which fire in both directions.

A yttrium-enhanced ground electrode transfers heat. The plugs carry a 5-year guarantee. Autolite also makes iridium, platinum and small-engine plugs for domestic and foreign vehicles. The company began in 1911 as a buggy lamp manufacturer, moved into spark plugs by the 30s and had made over 10 billion plugs by 2007.
