This is a universal coil The Pro Power HVC II Coil is completely built in-house so our engineers have exclusive control over their performance and qual­ity. The Coil utilizes an iron U-Core design with a segmented bobbin for improved voltage distribution. The bobbin is molded from Dupont Rynite FR946 material which has incredible dielectric capabilities at high temperatures. MSD also incorporated a cutting edge winding material that has an improved insulation and is also capable of enduring extreme volt­ages. Together, these materials create a durable coil with incredible voltage capabilities, lightning quick rise time and lengthy spark duration. The housing, also molded from Rynite material, features far spaced brass primary terminals and a well protected secondary tower for increased spark isolation. The housing is completely potted with an epoxy compound for vibration resistance and installs with sturdy vibration mounts. For use with MSD 7 and 8 Series Ignitions. Features Designed for racing applications with an MSD 7 Series Ignition Control New U-core winding design produces more voltage and current 70:1 turns ratio and lower primary resistance produce high voltage output Windings are encased in fracture resistant compound for vibration resistance Dupont Rynite housing with isolated tower and brass primary terminals Supplied with rubber shock mounts No CARB Exemption Order Number Brand MSD Color Red Emission Code 4 Inductance .250 mH Maximum Voltage 45,000 Volts Peak Current 2 Amps Primary Resistance .016 OHMs Product Type Coil Secondary Resistance 30 OHMs Spark duration 150 uS Turns Ratio 70:1 Type Drag Race / Long Duration Use Warranty Limited 1 Year Warranty Weight 3.75 lbs.
