Autolite 3136 Copper, Non-resistor Spark Plug
Core Feature
Autolite 3136 utilizes a copper core within the center electrode, which enhances heat conductivity. This helps in efficient heat dissipation, preventing overheating and ensuring consistent spark generation even under demanding conditions.
Design Specs
Typically featuring a standard J-gap configuration (often around 0.035 inches, though this may vary by application), it has a nickel-alloy outer electrode for durability. The thread size is commonly 14mm with a 3/4-inch reach, fitting many passenger cars, light trucks, and small engines.
Performance
The copper core promotes quick spark initiation, aiding in smooth engine startup, improved fuel efficiency, and reduced emissions. It’s engineered to withstand daily driving stresses, making it a cost-effective replacement option for older or moderate-use vehicles.
Compatibility
Suitable for a range of makes and models (e.g., certain Ford, Chevrolet, and Chrysler vehicles), though verifying fitment with the engine’s specifications or owner’s manual is recommended to ensure proper function.
Application
Ideal for older engines or those requiring a traditional spark plug design, it balances performance and affordability, catering to drivers seeking reliable ignition without advanced features like iridium or platinum.
