The Modified HEI Dust Cover allows you to remove the stock HEI coil in your distributor cap and replace it with an externally mounted coil such as the Blaster 2 Coil. This increases the reliability and the performance of the stock HEI system. The Modified Dust Covers are made from high quality plastic that resists spark loss and uses brass conductors to ensure low resistance connections. Designed to be installed on stock HEI distributor caps with no modification.
