70% More Spark Energy Than Stock!

Crane Cams FireBall E-Core coils are the most powerful available! FireBall coils produce up to 70% more spark energy than stock coils with outstanding reliability. Use of a Crane FireBall coil is mandatory to realize the maximum power output provided with Crane FireBall ignitions!

Features Include:
E-Core design with closed magnetic path. Reduced leakage inductance cuts losses and improves energy transfer to the spark plug.
Solid epoxy encapsulated. Resists severe shock and harsh vibration.
Insulated primary connector for greater safety E-core coils feature no exposed high voltage on primary terminals, an important consideration when used with high output CD ignition systems. Mating connector included with #270-730-0091. Other versions mate with O.E. connector.
SAE spec high voltage tower protects against arcing.
Crane's exclusive CAD (Computer-Aided-Design) windings produce maximum spark gap current and highest available voltage.
