## Overview

Autolite 4163 Copper Resistor Spark Plugs feature a full copper core electrode for enhanced thermal conductivity, a leak-proof copper-glass seal for durability, and a resistor to reduce interference and electrode wear. Designed for universal fit in cars and trucks, these plugs deliver quick starts, better fuel economy, and smooth acceleration, backed by Autolite’s trusted legacy since 1936.

## Description

Autolite Copper Core Spark Plugs deliver quick starts, good fuel economy, and smooth acceleration. The copper-glass seal bonds insulator and terminal post center electrode together to ensure full required voltage at spark gap, creating a gas-tight seal that is 100 percent leak-proof. Copper Core spark plugs feature a cold-formed steel shell and precision rolled threads, and a one-piece terminal post that adds strength. The multi-rib insulator reduces the danger of "flash-over" to prevent misfires, and the resistor reduces radio frequency interference (RFI) and electrode erosion. The full copper core electrode provides better performance in all conditions. Autolite Copper Core plugs are your industry standard.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Good price
*by P***T on January 12, 2025*

It works, fires the engine and at a good price

### ⭐⭐⭐⭐ Cheaper plug that works
*by C***G on September 28, 2024*

Cheaper then 1 ngk and they are lasting just as long fit the same

### ⭐ One plug not one box of plugs
*by D***A on May 21, 2025*

The spark plug itself is fine, but please be aware that you are ordering ONE individual spark plug, even though the description and the pictures show a box of four plugs.
