Your opinion on equal length spark plug wires?

How fast does electricity travel?

The timing difference between wires spanning an additional foot, short to long is insignificant.

About 300,000 kilometers per second. (or 671 million MPH)
I'm not going to even bother to figure out how long it takes to travel a foot.:D

Ok, it's 1.1 nanoseconds (called a "Lightfoot") and is how fast light travels one foot of distance. (electricity and light travel at real close to the same speed.)

Just think, if it was a car you were driving and you held the gas on for one second to long you would overshoot your destination by 300,000 km.
