Autolite Platinum Spark Plug – AP5405
Description

Description:
The Autolite AP5405 Platinum Spark Plug is designed to deliver dependable ignition performance, smoother starts, and improved fuel efficiency. Its platinum center electrode firing tip helps prevent gap erosion, allowing the spark plug to maintain a consistent spark and longer service life compared to conventional spark plugs.

A copper core center electrode improves heat transfer to maintain optimal engine temperatures and reduce fouling. The high alumina ceramic insulator provides excellent electrical insulation and thermal conductivity for reliable ignition performance. A multi-rib insulator helps prevent flash-over while the corrosion-resistant nickel-plated shell enhances durability and protects against rust and wear.

Autolite platinum spark plugs are engineered to provide reliable ignition performance for many gasoline engine applications, making them a dependable replacement option for maintaining efficient engine operation.
