why use a large gauge spark plug wires
What is High Tension Electricity? In all my engineering classes, never heard of it. I wouldn't use large gauge spark plugs unless they were specified. If you use them and they're not specified, you could ruin the spark plugs for too much voltage.
Wow, both answers are wrong and one that took engineering classes bashing on somebody that didnt. Both answers sounds dumb and foolish Spark plug wires. 99% of the larger wires is ONLY the outside jacket thats larger. Not the inner wound wire. Stock will be a 5mm to 7mm size. This is the size of the outside dia. An 8mm, 8.5mm, or 10mm plug wire will have the same size inside dia but with a thicker jacket on outside. This thicker jacket only helps to prevent nicks, rips, cuts in jacket that gets down to wire, also makes wire able to withstand a higher temp from under hood parts For the Mech. Eng.. Please tell me how you could ruin the spark plugs for too much voltage by using larger wires The voltage output in set up the coil. If the coil puts out 30,000 volts DC, then putting a 0 ga. wire on it will NOT change the amount of voltage that gets to the plug. A wire don't add voltage to the coil. Now the plugs resistance can and will change. A stock type wire may ohm out at 3,000 ohms per foot. This will keep some of the voltage from reaching the plug. Better, performance wires will ohm out at 50-400 ohms per foot, but this has nothing to do with the thickness of wire. Its the design and the carborn wound inner wire Lower ohms is better
Because of the High tension electricity that is produced
