Electrical Experts - Question re. Capacitor installation

Something new to my realm of expertise.  

I would like to install an electrolytic capacitor to act as a buffer for an ignition
system – sort of like placing a second battery up close to the load..  Since the
distance of the battery to the coil is about 7-8’ and my understanding that a circuit
may lag,  it seems installing a large capacitor might be a good idea.   If so, it makes
sense that I’d install it in parallel with respect to feed wire and ground, however
diagrams for most stereo AMP installations show the cap to be inline, with no other
current path to the amp.

Is it OK to install an electrolytic cap. as sort of a buffer or quick discharge
batteryin parallel with the circuit?  That is basically to connect the positive end to
battery post near load and ground as normal, leaving the original positive feed path
intact.  I have some 1 and 2 Farad caps  and this is mainly to prevent lag at high RPM,
similar to stereo clipping at high volume.

Good Idea or ???  I’m doing some searches, but not finding a solid answer.
