2021-22 Circle Track Catalog

Ignition Wire Sets and Accessories Universal wire sets have the spark plug boot and terminal fac- tory installed. The distributor end boots and terminals are sup- plied, but are not crimped on. Wires are extra long and include a mini-stripper/crimper to aid installation. Super Conductor 8.5mm Spark Plug Wire Sets Have extremely low resistance and high RFI (radio frequency interference) suppression; a combination which would seem to defy the laws of physics. The low resistance is the result of a he- lically wrapped, copper alloy conductor, which is then wrapped around a ferro-magnetic impregnated center core. Available in red or black. 2-in-1 Universal Sets Includes terminals for 8-cylinder engines with early- (socket) and late-type (HEI spark plug top) distributor caps. Multi-angle boots and terminals are factory-installed on one end.

Multi-angle boots and terminals are factory installed on one end. 2-in-1 Universal Sets Set includes terminals for 8-cylinder with early- (socket) and late-type (HEI spark plug top) distributor caps. 90° boots and terminals are factory-installed on one end.
