|Aftermarket plug wires are either always too short, or too long, and never fit correct. This example is of an MSD Custom Fit set.
||Factory plug wires are always the correct length, and fit just like they were new. No tie wrapping! All factory wires are noise suppression wires, meaning no radio noise!
||Factory plug wires are also designed to fit back into the OEM plug wire retainers used to keep the wires away from moving parts and exhaust components. Having plug wires in their proper holders is essential to prevent arcing and power loss.|
