High energy coil for GM HEI distributors with enhanced spark performance.
The MSD Ignition HEI Coil is designed as a direct replacement for stock coils in GM HEI distributors, providing a significant boost in spark energy. With a maximum output of 42000 volts and a low primary resistance of 0.31 ohms, this coil ensures optimal performance, especially at higher RPMs. The unique construction features low inductance and high temperature windings, allowing for faster charging and more powerful sparks, which are crucial for efficient combustion.
This coil is engineered to deliver full power sparks up to 9000 RPM when paired with the MSD HEI module, making it suitable for both street and race applications. The epoxy filled design enhances durability, ensuring that the coil can withstand the rigors of daily use and harsh racing conditions. Additionally, the 70:1 turns ratio contributes to its high voltage output, making it a reliable choice for performance enthusiasts looking to enhance their ignition system.
