Does thicker ignition wires boost the wngine power?

Can somebody tell - Does thicker ignition wires increase the engine power?

redux
short answer, no on the stock car, not modified with say super powerful MSD ignition systems, (racing parts upgrade)
long answer but shorter.
no unless yours are bad now,.! this is a fact.
seeing how cant see yours, now , or know how old it is or what someone put there, long ago, or the NEW ones promising more power from engine (lies) I cant elaborate more.

short answer NO.

try to know that there are vast numbers of insulation materials.
and the poor grades need to be thicker, see?
the limit here is wires must flex. so can NOT be made of glass or ceramic, (like your AC power company uses in 1million volt transmission lines)
but must be made of plastics, and there are vast numbers of plastics. Silicon rubber is popular sure. and good.
and the outer layer needs to be fuel and oil proof.
so many wires are in layer. for that reason.

if the car is stock the stock wire work perfectly ! (for spark) how long they last?, is another parameter....
if you buy mag wires, the wire and the insulation is better and runs LONGER. lasts...

power is never gained ever, unless car is not stock or the wires in the car are bad, as all seem to do after 60k miles,
the other issues is vibration, the stock carbon wires, love to fail with vibration and this engine shakes, it has no SILENT SHAFT balancer in the block.

just buy the $30 BOSCH mag wires, you will not be sorry you did, and wallet happy and zero hype on wires.
if rich?, NGK blue mag wires, the mag wires are coils, and are inductive, they use inductive reactance to get the RFI noise down. (not silly weak carbon string)
the best prices, google the Bosch partnumber to find them, many times on ebay they have over stocked parts, at 1/2 price...

Thank you! I bought the BOSCH ones

tbey can tell that lie for 2 reasons(more)?
1: yours are bad , there's are not.
2:your running 100,000 volt racing msd on a turbo engine, so yes.

sure overkill on insulation can be justified, (paranoia?)
but only if you are running them longer that OEM replacement times, 60k? 100K miles
so if you want them to last 500kmiles sure? Its your car, your goals.
but if the wires inside are not wire, but are carbon or the silicon snot, gee, that fails first.
NGK mags are plenty good.

Most wires are good for 60k. and will not flash over in that time frame. ever.
brand names, not feabay "som ting wong"brands for $5 a set.
