The points-based ignition systems found in early 8-cylinder engines can be unreliable and difficult to maintain, as the points wear out over time and require frequent adjustments. This can lead to poor engine performance, hard starting, and even engine misfires or stalls. By replacing the points and condenser with the 1181 ignition system, you can eliminate these issues and enjoy improved engine performance and reliability. It requires virtually no maintenance and can be installed quickly and easily, making it a popular upgrade for classic car enthusiasts. This unit is a replacement for the 1181 Ignitor, providing a cost-effective solution for repairing your vehicle. The 1181 Igniter is designed to fit Delco 8-cylinder distributors with a windowed type distributor cap and is compatible with a wide range of classic American cars and trucks from 1957 to 1974. The 1181 Ignition delivers a more precise spark to the engine, ensuring optimal ignition timing and better combustion. The 1181 Electronic Ignition Conversion Kit is specifically designed to fit Delco 8-cylinder distributors with a windowed type distributor cap. Solid-state electronics: The 1181 Electronic Ignition features a solid-state electronic ignition module that replaces the traditional points and condenser. This provides more precise ignition timing and eliminates the need for routine points adjustments. Increased reliability: Because the 1181 Electronic Ignition is solid-state and has no moving parts, it is much more reliable than a traditional points-based ignition system.
