MSD Blaster GM Coils

4.48 out of 5 stars 85 Customer Reviews

MSD Blaster coils give your GM maximum voltage output! With windings and construction similar to MSD's Blaster 2 coils, these have an increased turns ratio, plus lower primary resistance than your stock coils. The Blasters will work with stock GM coil ignition systems, as well as MSD-equipped cars and trucks. Looking to get a little more output voltage from your GM ignition system? Just bolt in one of these MSD Blaster Coils.
