Description

The Autolite AR3910X is a racing spark plug designed as a beneficial upgrade to the ignition system. This surface gap plug requires no gap settings, making it a simple plug-and-play part for clone engines, including the 212cc Predator and BSP engines.

It features an Yttrium-enhanced alloy that helps reduce sidewall temperature for improved durability and less pre-ignition. The plug is designed with a colder heat range than stock plugs to support performance modifications and handle intense conditions. Additionally, it has a cut-back ground electrode for better flame kernel ignitability and is coated in anti-corrosive nickel plating to prevent rusting.
