This listing is for a case quantity of 24 IGN-1A smart race coils. You’ll receive the exact same high-performance IGN1-A coil, but at a discounted bulk price. Perfect for resellers, engine builders, or serious enthusiasts — we aim to be your Warehouse Club for ignition coils! The IGN1A Smart Coil by AMP EFI delivers 103 mJ of spark energy with a 2.9 ms duration, outperforming many capacitive discharge systems—no CDI module needed. These high-output coils feature a 19-amp IGBT ignitor built in, making them perfect for coil-per-plug setups in high-performance engines. Compatible with MS3Pro and MS3X directly, and adaptable for MS1/2 with a pull-up resistor, they provide reliable and powerful spark control for extreme builds. While designed for sequential or wasted spark systems, they are not recommended for distributor use due to thermal limits. Available with either a 4' flying lead pigtail or a connector and pins kit. Features Delivers 103 mJ per spark, 2.9 ms spark duration 19A built-in IGBT ignitor Coil-per-plug compatible with MS3X/MS3Pro (5V logic) Works with MS1/MS2 using 270–330 ohm pullup resistor Not for use in distributor setups (max 40% duty cycle) Requires HEI-style plug wire boots “The Hulk” from Street Outlaws No Prep Kings uses these! Electrical Specifications Max output voltage: 81,000V Minimum output voltage (at recommended dwell): 40,000V Output energy: 103 mJ Spark duration: 2.9 ms Primary resistance: 0.5 ohm (nominal) Primary inductance: 4.8 mH Secondary resistance: 8,500 ohm Secondary inductance: 22.5 H Turns ratio: 71.1 Max current: 19A Max battery voltage: 17V Nominal dwell: 3.0 ms Connector Pinout A: Signal from ECU (5V logic) B: Logic ground (to ECU) C: Spark ground (to cylinder head) D: Power ground (to battery) E: 12V power input Included Options Option 1: 4’ Flying Lead Pigtail Option 2: Connector with Crimp Pins Note: Exceeding dwell or duty cycle can damage the coil. No manufacturer warranty is offered—intended for motorsports use.
