Autolite - Double Platinum Spark Plug

The Autolite Double Platinum Spark Plug features a platinum-to-platinum design that prevents gap erosion, reduces misfires, and extends the spark plug's life. Engineered with a yttrium-enhanced ground electrode for superior heat transfer, it ensures optimal performance under high temperatures and pressures. The high alumina ceramic insulator provides excellent thermal conductivity and dielectric strength, while the multi-rib insulator design prevents flash-over. Ideal for vehicles with distributorless ignition systems (DIS), this spark plug offers improved fuel efficiency and easier starts compared to standard plugs. Backed by a 5-year limited warranty.
