AEM 4 Channel Coil Driver for High-Power Two-Wire Coils

The AEM 4 Channel Coil Driver for High-Power Two-Wire Coils provides external control of four independent ignition channels, enabling stable spark delivery across all cylinders for measurable combustion consistency.

By relocating high-current switching out of the ECU, it reduces thermal and electrical stress on the control unit and maintains precise coil charging at elevated RPM. The module architecture addresses common OEM limitations when running high-output two-wire coils, ensuring reliable ignition performance in demanding conditions.

Features & Benefits

• Four independent ignition channels – Dedicated control per cylinder improves timing accuracy and uniform spark energy across the engine.
• Optimized for high-power two-wire coils – Ensures proper dwell and discharge characteristics for robust spark under boost and high RPM.
• External driver module – Offloads high-current coil control from the ECU to protect sensitive electronics and enhance system reliability.
• Precise control for consistent combustion – Stable coil actuation supports smoother operation and repeatable performance tuning.

Technical Specifications

• Channels: 4 independent ignition outputs
• Coil compatibility: High-power two-wire coils
• Architecture: External driver module (ECU offload)

Compatibility

Universal for ignition systems using high-power two-wire coils where the ECU requires an external coil driver, including standalone engine management and compatible OE-style control strategies.

Closing

Engine builders and calibrators gain dependable, repeatable ignition performance for two-wire coil applications in motorsport and high-demand tuning environments.
