IGN-1CD Capacitive Discharge Ignition Coil

The IGN-1CD is a high-performance capacitive discharge (CDI) ignition coil designed for motorsport use. Compact, reliable, and cost-effective, it’s ideal for use in distributor-based CDI systems or coil-per-cylinder setups—perfect for engines requiring precise, high-voltage spark delivery under extreme conditions. Vibration-resistant and capable of being mounted at any angle, this coil is compatible with most CDI boxes including MSD, Mallory Hyfire, and other aftermarket capacitive ignition systems. Unlike many CDI coils, the IGN-1CD includes a dedicated secondary ground terminal, improving isolation between primary and secondary circuits and ensuring clean, stable ignition performance. It uses standard HEI-type spark plug wire boots and delivers exceptional spark energy when configured with appropriate dwell settings. Note: Excessive dwell or high duty cycles may lead to coil failure. No warranty is provided. Key Features Compact CDI race coil designed for high-performance applications Fully compatible with MSD, Mallory Hyfire, and similar CDI boxes Designed for use in both single-coil distributor and multi-coil systems Vibration-resistant and angle-mountable Secondary ground for improved noise isolation and reliability Uses HEI-style spark plug wire boots Connector Pinout A (Positive) – Connect to CDI box coil + output (e.g., MSD orange wire) B (Negative) – Connect to CDI box coil – output (e.g., MSD black wire) C (Secondary Ground) – Connect to cylinder head or engine ground
