FAQ
What does the Pertronix LU-145 kit do?
It replaces the breaker points inside Lucas D3A4 4-cylinder distributors with a self-contained Ignitor electronic module, ending point wear, misfire, and periodic point adjustment.
Does this kit need an external ignition box?
No. The module fits inside the original distributor and keeps the stock appearance, so no separate ignition box is required.
How do I confirm the kit fits my distributor?
Fitment is distributor-based. Match your distributor model against the Pertronix application list, or use the Pertronix Distributor Lookup, before ordering.
