NAPA Autolite Iridium Spark Plugs

Description

The Autolite Iridium range is manufactured with an iridium-enhanced center electrode, designed to eliminate gap erosion and provide more focused ignition and impressive durability. A copper glass seal bonds the ceramic insulator and center post together ensuring a strong spark and a 100% leakproof seal. Coupled with a cold-formed steel shell and precision rolled threads, Autolite spark plugs exhibit great durability and anti-seize properties.

• Iridium-enhanced center electrode resists wearing due to extreme temperatures, oxidation, and corrosion.
• More focused ignition for improved ignitability, optimum performance, and better fuel burn.
• Nickel-plated shell and threads for increased protection against corrosion and improved service life.
• Platinum protected ground strap for high efficiency and durability for all ignition types.
• Iridium-enhanced 0.6mm finewire design for optimal durability and performance.
• V-trimmed ground electrode for improved ignitability.
• Platinum protected ground wire for maximum efficiency in all ignition types.
