The Blaster HVC Coil works great on the street or strip. Designed to produce maximum power with an MSD6 Series Ignition Control, this coil will produce high voltage for long durations. It works great on road courses and circle tracks. Low primary resistance allows the coil to take the energy from the MSD and instantly step up the voltage with a high amount of current. This will deliver a powerful spark to the plug to ensure complete combustion of the cylinder. The coil windings are encased in epoxy and held in an aluminum housing. Featuring a tall secondary tower that accepts an HEI style plug terminal and boot. Comes with heavy-duty vibration mounts for a secure mount. Note: Not legal for sale or use on pollution controlled motor vehicles.
