PER MSD it depends on which part number you have.


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 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

Key words -It is recommended -does not say you have to
