Igniter II Conversion Kit Lucas 25D4 4-Cyl.

The Igniter II Conversion Kit Lucas 25D4 4-Cyl. is a modern solid-state ignition upgrade designed for classic and vintage four-cylinder engines that utilize Lucas distributors. This kit is perfect for automotive enthusiasts and mechanics who are restoring British Leyland vehicles, including Austin-Healeys and MGs, providing a reliable ignition solution.

This electronic conversion replaces the traditional mechanical points and condenser systems with advanced transistorized ignition technology. It features an optical sensor and a solid-state control module that accurately reads rotor position, ensuring consistent spark timing across the RPM range. This design eliminates common issues associated with original Lucas systems, such as point bounce and dwell variation, enhancing overall performance.

Ideal for restoration builds, vintage racing, and daily drivers, this kit retains the original distributor housing and cap for straightforward installation without the need for costly modifications. The Igniter II system provides superior dwell stability, leading to improved cold-start reliability, idle quality, and fuel efficiency in carbureted and early fuel-injected four-cylinder engines.
