Autolite Platinum Spark Plug

Description

The Autolite Platinum Spark Plug (AP5144) draws on over 100 years of engineering experience from a brand that has produced more than 11 billion plugs. The AP5144 was designed and engineered in the USA with premium materials chosen to resist wear and deliver reliable ignition over an extended service life. A necked-down center electrode paired with a full platinum firing tip forms the core of the plug's ignition system, while a high nickel alloy side electrode completes the assembly. The OE-compatible design allows for straightforward installation as a direct factory replacement. Autolite also offers double platinum and iridium XP plugs for drivers seeking additional performance gains.
