Ignition systems set up for racing or high performance street use put high demands on ignition components. The continuous high voltage required can destroy poorly constructed ignition parts. Taylor Distributor Caps and Rotors are injection molded with the highest quality materials and manufacturing process available. Produced to deliver high performance and long life, Caps and Rotors are made from an alkyd molding compound that provides superior protection from cross firing and arcing. The compression molded caps are stress-relieved after molding to ensure dimensional integrity.
