Key Technical Features

• Voltage Rating: 12 V DC – compatible with standard automotive electrical systems.
• Output Energy: Optimized for high‑efficiency spark production, ensuring consistent combustion across a wide range of operating temperatures.
• Construction: Robust ceramic insulator and copper windings provide excellent thermal stability and resistance to electrical arcing.
• Mounting Design: Standardized bolt pattern for seamless integration into OEM and aftermarket engine assemblies.
• Operating Temperature Range: -40 °C to +120 °C, suitable for both high‑performance and everyday driving conditions.

Compatibility Overview

The GN10572‑12B1 is engineered to fit a broad spectrum of vehicles across multiple manufacturers. Its versatility makes it an ideal choice for:

• BMW: Models ranging from the 1 Series (E81/E87) to the 3 Series (E46, E90, F30), as well as newer X models.
• Citroën & Peugeot: Including the C4, C5, DS series, and Mini variants.
• DS & MINI: Engineered to meet the ignition demands of compact and mid‑size engines.
• Other OEM platforms that specify a single‑coil, 12 V ignition system.

Because the coil is an OEM replacement part, it matches the original specifications for spark timing, voltage output, and mechanical fitment. This ensures optimal engine performance without compromising reliability.

Installation Highlights

1. Remove Existing Coil: Detach the old ignition coil by loosening the mounting bolts and disconnecting the electrical connector.
2. Align New Unit: Position the GN10572‑12B1 in place, ensuring that the terminal aligns with the spark plug wire or module.
3. Tighten Securely: Fasten the mounting bolts to the manufacturer’s torque specifications to prevent vibration damage.
4. Reconnect Wiring: Attach the electrical connector, verifying a secure connection before closing the engine bay.

Following these steps guarantees that the ignition coil operates within its designed parameters, delivering consistent spark timing and maximizing fuel efficiency.

Performance Benefits

• Enhanced Combustion: The precise spark output improves combustion efficiency, leading to smoother engine operation.
• Reduced Emissions: Efficient ignition reduces unburnt hydrocarbons, contributing to lower tailpipe emissions.
