- Our famous red canister coil! Great choice with an MSD 6-series ignition. If you are looking to upgrade your stock coil, or want to compliment the performance of your MSD Blaster Ignition, MSD 5, 6, or 7, the Blaster Coil line is the right choice. Our Blaster Coils are designed for improved spark output! Special 100:1 windings are used to provide maximum build-up of voltage! These windings are held secure and kept cool in an oil-filled metal canister. The Blaster Coil is designed to mount in most factory canister coil mounts. MSD also offers a Chrome Coil Bracket, PN 8213. It is recommended to mount the PN 8202, PN 82023, and 8223 coils in an upright position. The High Vibration Coil, PN 8222, can be mounted in any position due to its epoxy potting compound.
