High performance spark plug cable sets Taylor Pro-Spark Matching color candle caps are connected directly to the cable, in pre-cut kits specific to the motorcycle model described. The 'Pro-8' cables are made of highly driving materials - the core is heat-treated and has two conductors that act as a mini resistance circuit in parallel. The result is a cable that has 1/10 of the resistance of normal spark plug cables, provided with shielded protection that can be of great importance with stereo, CB radio or sophisticated electronic ignitions. It is appropriate for pin or electronic ignitions in track or road applications.
