How it works

Fully electronic, 123 Ignition distributors have no contact points and therefore no rubbing parts. There is no wear.

On top of this added reliability, 123 Ignition electronic distributors are, unlike bob-weight distributors, more precise and responsive, giving your engine more flexibility. They also improve fuel consumption.

Advance curves and programming

This model contains 16 preset advance curves to choose from to suit your engine. Once you have checked the curve number for your vehicle in the instructions, simply unscrew a nut to reach a rotary selector and set it to the right curve.

The model-specific advance curve is factory-set and cannot be changed, as an incorrect setting could damage the engine.

Fitting and setting up

The distributor comes with fitting and setting instructions and installs in under 10 minutes directly in place of your original distributor.

Setting up is very simple thanks to a built-in LED that lights once the timing is correct. You then have the optimum advance for smooth running.
