Autolite 144 Copper Resistor Spark Plug
Autolite 144 is a copper resistor spark plug built for quick starts, steady ignition performance, improved fuel economy, and smooth acceleration. It is an OE-style replacement for a wide range of foreign and domestic vehicles, including many Honda Civic and Toyota Corolla applications that call for a 14 mm tapered-seat plug.
Key Features
- Copper center electrode for reliable spark delivery
- Resistor design with 5,000 ohm resistance
- Nickel center and ground electrode tip materials
- Tapered ground electrode tip design with one ground electrode
- Pre-gapped to 0.034 in. (0.90 mm)
- 14.0 mm thread diameter, 5/8 in. hex size, and 0.431 in. reach
- Ceramic insulator with short insulator type
Product Details
The Autolite Copper Resistor Spark Plug line focuses on OE form, fit, and function for everyday service work. Part number 144 uses a copper core center electrode for consistent conductivity, while the resistor construction helps reduce electrical noise in the ignition system. Its tapered seat, standard regular center electrode design, and nickel electrode tips make it a practical replacement choice for vehicles that specify this plug style. This part cross-references Champion Spark Plug 121 for the same application.
Common Issues It Can Address
- Hard starting caused by worn or fouled spark plugs
- Rough idle from weak or inconsistent spark output
- Reduced throttle response during acceleration
- Ignition misfire from excessive plug wear
- Radio-frequency interference in resistor-plug applications
Installation Notes
Verify the vehicle’s required thread diameter, reach, seat type, and pre-gap before installation. Autolite 144 is a 14 mm tapered-seat spark plug with a 0.034 in. pre-gap, so confirm those specifications against the service information for your Honda Civic, Toyota Corolla, or other listed application before use. Inspect the ignition system, coil condition, and plug wires during service, and torque the plug to the manufacturer’s specification.
Quality Assurance
Autolite supplies ignition products for the automotive aftermarket and original equipment manufacturers, with a focus on OE-style fit and function across many makes and models. Part number 144 is built to meet the dimensional and material requirements expected for routine spark plug replacement.
