I was wondering how long is to long for coil wires. I have a trophy truck and plan on mounting my coils out of the way and under the dash. do I need to be concerned on the lenght? also should I try to keep the lengths on each one close to the same? I'm assuming the shorter the better and yes on trying to keep them all the same lenght. but what your guys opinion? I'm running a 5.3 with the pantera efi computer and gen 4 coils.

 

Hi Brent, the wire length should be the same if possibly.
The wire resistance has NO effect on energy to the plug if within the common range.
The FACT is that a small amount of wire resistance is GOOD for an increase in the time that the spark occurs inside the combustion chamber.
This "Arc Duration" is also effected by the Spark Plug Gap.

Your OEM style ATI Dampener has arrived to my shop, the one from Wegner.
