DESCRIPTION

AUTOLITE Copper Core Spark Plug — Reliable Ignition Performance

Brand: AUTOLITE

The Copper Core Spark Plug delivers dependable starts, consistent combustion and long service life. Engineered for efficient energy transfer and durable operation, it’s an ideal choice for a wide range of gasoline engines.

Key Features

  • Copper core electrode: Full copper center provides superior thermal conductivity and reliable performance in all conditions.
  • Copper-glass seal: Bonds the insulator, terminal post and center electrode for a 100% gas-tight, leak-proof seal and consistent voltage at the spark gap.
  • Multi-rib insulator: Reduces risk of flash-over for cleaner, more stable ignition.
  • One-piece terminal post: Adds mechanical strength and durability.
  • Built-in resistor: Minimizes radio frequency interference (RFI) and helps reduce electrode erosion.
  • Cold-formed steel shell: Precision rolled threads ensure secure fit and long-lasting thread integrity.

Notes

Always verify cross-reference listings and compatibility with your vehicle before purchase to ensure proper fit and optimal performance.
