MSD Powersports Harley-Davidson 8.5mm Spark Plug Wires
MSD 8.5mm Super Conductor Spark Plug Wires transfer spark from the coil to the plug with a minimal loss of spark energy while suppressing Electro Magnetic Interference (EMI). MSD uses a special copper conductor keeping resistance under 50 ohms per foot! Even with this low resistance, the wire retains high EMI suppression capabilities. By wrapping the conductor tightly around a ferro-magnetic impregnated center core an EMI choke is created keeping any interference inside the wire.
The Super Conductor wire is a high performance wire from the inside out. The outer sleeve is a combination of silicone and synthetic materials for supreme resistance against heat, chemicals and abrasion. Thick boots with more material also help guard against spark arcing to ground and special dual crimp terminals grip the conductor and the sleeve of the wire so there is no chance of the terminal pulling off the wire.
Harley-Davidson Custom Wire Kits are made black to keep the OEM look.
