Your components like to work on a nice steady voltage - DC.
Because they are electronic, they are able to react to the electrical "noise" generated by the engine's electrical system.
Electronics are much more sensitive to this "noise" - random spikes of extra voltage, than the old electromechanical components.
As an analogy, imagine the spikes as flash floods running down a river.
A capacitor acts a bit like the flood plains along the river, soaking up the extra volume and smoothing out the flow.
Definitely worth a try fitting one.
Any bit of wire in the system can collect energy from the "spikes", so a capacitor should be fitted as close as possible to the thing you are trying to protect, with as short leads as practicable.
