The Pertronix LU-143A Ignitor is a points-to-electronic ignition conversion kit for British four-cylinder engines using the Lucas 43D, 44D, 45D or 59D series distributor, found on many MG and Lotus models. It replaces the points and condenser with a self-contained magnetic-trigger module for reliable starting and a stronger spark. The kit runs on a 12-volt negative-ground system. Fitment is by distributor, so confirm the Lucas distributor series against the Pertronix list before ordering.

FAQ
What does the Pertronix LU-143A Ignitor kit do?
It converts the original breaker-point ignition to electronic. The Ignitor replaces the points and condenser inside the existing distributor with a self-contained magnetic-trigger module, so the engine starts more reliably, holds timing better, and needs no points to clean, gap or replace.
What does the Pertronix LU-143A fit?
It is designed for Lucas 43D, 44D, 45D and 59D series 4-cylinder distributor (British). Fitment is determined by the distributor, so check your distributor against the Pertronix fitment list before ordering.
What electrical system does the LU-143A require?
It is built for a 12 volt negative ground system. Confirm your vehicle matches this voltage and ground polarity, because Ignitor kits are voltage and ground specific.
Does the LU-143A need any maintenance or a special coil?
No routine maintenance is required once installed, and there are no points to re-gap. It works with the vehicle's existing coil or a compatible Pertronix Flame-Thrower coil that matches the system voltage.
