Spark Plug Wires Separators

5 products

Spark Plug Wires Separators for Harley-Davidson keep your ignition leads neatly routed and safely spaced from hot engine surfaces. Available through Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, our range features spark plug wire separators from MCS. These universal-fit separators work across the entire Harley-Davidson line-up, from vintage Shovelheads and Panheads to modern Twin Cam and Milwaukee-Eight engines. Properly routed spark plug wires prevent heat damage to the insulation, reduce the risk of crossfire between cylinders and give the engine bay a cleaner, more organised appearance. Over time, unsecured leads can melt against exhaust pipes or rub through on sharp edges, leading to misfires and hard starting. Fitting quality separators is a simple, inexpensive way to protect your ignition system and improve the overall look of your engine. Each separator is designed to accommodate standard Harley-Davidson plug wire diameters for a secure, vibration-resistant hold. Browse the full range below.
