The AMP EFI IGN-1CD is a high-performance capacitive discharge (CDI) ignition coil engineered for motorsport applications. Its compact, reliable, and cost-effective design makes it suitable for both distributor-based CDI systems and coil-per-cylinder configurations, delivering precise, high-voltage spark delivery essential for engines operating under extreme conditions. A key feature is its dedicated secondary ground terminal, which enhances isolation between primary and secondary circuits, contributing to clean and stable ignition performance. The IGN-1CD utilizes standard HEI-type spark plug wire boots and is capable of delivering exceptional spark energy when paired with appropriate dwell settings. It is important to note that excessive dwell or high duty cycles may lead to coil failure, and no warranty is provided for this product. Key features include its compact CDI race coil design for high-performance use, full compatibility with MSD, Mallory Hyfire, and similar CDI boxes, and suitability for both single-coil distributor and multi-coil systems. Its vibration-resistant and angle-mountable design, along with a secondary ground for improved noise isolation, further enhance its reliability.
