Bosch 12-13-7-575-010 Pencil Ignition Coil for BMW and Mini Cooper

The Bosch 12-13-7-575-010 is a pencil-style coil-on-plug ignition coil designed for BMW and Mini Cooper vehicles. This direct ignition system component mounts directly onto the spark plug, eliminating the need for spark plug wires and providing more efficient spark delivery to the combustion chamber.

Key Features:

• Pencil-type coil-on-plug design for direct spark delivery
• 12-volt operation with 3-terminal blade connector design
• Features center guide tab for proper alignment and installation
• No external resistor or oil filling required
• Transforms 12V battery voltage into approximately 30,000 volts needed for ignition
• OEM-quality replacement part meeting original equipment specifications

This ignition coil is a critical engine management component that converts low battery voltage into the high voltage necessary to create the spark that ignites the air-fuel mixture in the engine cylinders. Common symptoms of a failing ignition coil include rough idling, misfires, hard starting, poor acceleration, decreased fuel efficiency, and check engine light illumination.
