Autolite Platinum Spark Plug
Description
The Autolite Platinum Spark Plug brings over 100 years of Autolite engineering expertise to your engine's ignition system, backed by more than 11 billion plugs sold worldwide. Autolite designed and engineered this plug in the USA, and the brand stands behind the product as an official NASCAR performance partner. The AP104 is a direct OE-replacement plug built around a platinum-tipped center wire that outlasts standard designs in both gap stability and spark consistency. Premium electrode materials and a necked-down firing profile help the plug perform closer to factory specifications even at high mileage. Drivers looking for further gains can upgrade to Autolite Double Platinum or Iridium XP plugs for an even longer-lasting firing tip.
