Autolite Platinum Spark Plug – AP104
Description

Description:
The Autolite AP104 Platinum Spark Plug is engineered to deliver dependable ignition performance, smoother engine starts, and improved fuel efficiency. Its platinum center electrode firing tip helps resist gap erosion, allowing the spark plug to maintain a consistent spark and longer service life compared to conventional spark plugs.

The copper core center electrode improves heat transfer to help maintain optimal engine temperatures and reduce fouling. A high alumina ceramic insulator provides excellent electrical insulation and thermal conductivity for reliable ignition performance. The multi-rib insulator design helps prevent flash-over, while the nickel-plated shell resists corrosion to help extend spark plug durability.

Autolite platinum spark plugs are designed as reliable replacement components for a wide range of gasoline engines, delivering consistent performance and dependable engine operation.
