MSD Ignition 121-31183K Features:

MSD's Universal Spark Plug Wire Sets are available in your choice of black or red wire for a variety of applications and include a spark plug terminal and installed boot with one open end. The set also includes distributor cap boots and terminals so the wire can cut to a specified length and installed with the supplied mini-stripper-crimper.

MSD's Replacement Spark Plug Wires and Coil Wires are made with the same Super Conductor wire as their universal and pre-made sets, just longer than normal for custom tailoring when you need that extra length.

Features:

Only 40-50 ohms resistance per foot of wire (lowest of any helically-wound wire)
MSD Ignition Copper alloy conductors result in less spark energy loss so more reaches spark plugs
Over 40 feet of conductor per foot of wire
Conductors are wrapped around ferro-magnetic center cores, which effectively suppresses electro magnetic interference
Outer sleeves consist of silicone and synthetic material for a strong resistance to heat, abrasion, and tearing.
