Autolite Copper Spark Plug

Autolite 4132 is a copper non-resistor spark plug built for OE-style form, fit, and function. It is listed for Lamborghini Diablo, Countach, LM002, and LM American applications, with fitment notes that confirm the required gap and OE-style specification.

Key Features

• Copper center electrode for reliable ignition performance.
• Nickel ground and center electrode tip materials for consistent spark delivery.
• Non-resistor design for applications that call for a resistor-free plug.
• Flat seat, 12.0 mm thread diameter, and 0.750 in. reach.
• Short ceramic insulator with a removable nut terminal.
• Pre-gapped to 0.028 in. for this part configuration.

Detailed Description

Autolite 4132 is engineered as an OE-style replacement spark plug for select Lamborghini models, including Diablo, Countach, LM002, and LM American. The copper core supports quick starts and smooth acceleration, while the nickel electrode materials and tapered ground electrode design help maintain stable ignition performance. This part number, 4132, is a direct fit reference for applications that specify a copper non-resistor spark plug with a flat seat and 12.0 mm thread.

Autolites Copper Non-Resistor Spark Plug line focuses on practical ignition performance and OE-style replacement fitment. For buyers searching for a Lamborghini Diablo spark plug or a Lamborghini Countach spark plug, 4132 matches the listed application requirements and configuration details.

What It Helps Address

• Hard starting caused by worn or incorrect spark plugs.
• Rough idle from inconsistent ignition output.
• Slow throttle response during acceleration.
• Fuel economy loss related to degraded spark performance.
• Misfire concerns when the application calls for a non-resistor plug.

Installation Notes and Tips

Verify the application notes before installation, including the specified gap for the vehicle and engine configuration. Confirm the seat type, thread diameter, reach, and terminal style match the original specification. This part cross-references OSC 4076 and A10 for the same application.

Quality Assurance

Autolite supplies ignition products to the automotive aftermarket and original equipment manufacturers, and this spark plug is built to OE form, fit, and function standards for the listed applications.
