Detailed Product Description

The Autolite Copper Non-Resistor Spark Plug 4194 features a copper core center electrode that provides excellent electrical conductivity, promoting efficient spark generation. The nickel ground electrode with a tapered tip design enhances durability and consistent spark gap maintenance. This spark plug uses a flat seat type to ensure a secure fit and proper sealing within the combustion chamber. The short ceramic insulator offers effective heat dissipation and electrical insulation. With a removable nut electrical terminal, the plug allows for straightforward installation and connection. The pre-gap size of 0.025 inches (0.60 mm) is factory set to optimize ignition timing and combustion efficiency. This spark plug is designed without a resistor, making it suitable for ignition systems that do not require resistor plugs.

About the Copper Non-Resistor Spark Plug Product Line

Applications and Common Issues Addressed

• Replacement for worn or fouled spark plugs in compatible vehicles
• Resolves misfires caused by poor spark conduction
• Improves cold start performance and throttle response
• Addresses rough idling due to inconsistent spark gaps
• Helps reduce engine hesitation and power loss

Installation Notes and Tips

Ensure the spark plug gap is checked before installation, although the pre-gap is factory set at 0.025 inches (0.60 mm). Use a 5/8 inch (16 mm) socket wrench for proper torque application. Avoid over-tightening to prevent damage to the flat seat and threads. The removable nut terminal allows for easy connection to the ignition wire. Always consult the vehicle’s service manual for specific torque specifications and compatibility.
