MSD Blaster coils put out 45,000 V, which are 15,000 more than stock. They also have an oil-filled metal canister and will fit stock mounting brackets.
For off-road, marine, racing, or other extreme environments, MSD Blaster High Vibration ignition coils are the best choice. Their sturdy metal housing is potted with a premium-grade epoxy to completely encase the coils' primary and secondary windings. This protects the coils from high and low frequency vibrations. Alkyd material is used to form the spark tower because of its high dielectric characteristics. Alkyd will not carbon track when high voltage is passed across its surface. For your convenience, a standard canister-type coil mount can be used, and the coils can be mounted in any position.
When used with an MSD 6 Series ignition, these MSD Blaster SS coils delivered 300 milliamps and 40,000 V of spark. The coils feature efficient E-core windings, brass terminals, and a durable Rynite housing.
Looking to get a little more output voltage from your GM or Ford ignition system? Just bolt in one of these MSD Blaster Coils. With windings and construction similar to MSD's Blaster 2 Coils, these coils have an increased turns ratio, plus lower primary resistance than your stock coil. The Blasters will work with stock GM or Ford coil ignition systems as well as MSD-equipped cars and trucks.
Now you can replace your stock coil with theses High Energy Unitized Coil for HEI Distributors. This coil has low inductance, high temperature windings which charge the coil faster to give you increased spark energy at higher rpm.
