Bosch 0221504001 Direct Ignition Coil without Spark Plug Connector

The Bosch 0221504001 is an Original Equipment (OE) quality direct ignition coil designed for select Mercedes-Benz applications. This precision-engineered ignition coil transforms the vehicle's 12-volt battery voltage into approximately 30,000 volts required to create the high-energy spark that ignites the air-fuel mixture in the combustion chamber.

Key Features:

• Original Equipment quality ignition coil manufactured to Bosch specifications
• Direct ignition coil design for precise spark delivery
• Transforms 12V battery voltage to approximately 30,000V for optimal ignition
• High-quality materials provide excellent resistance to heat, vibration, and corrosion
• Manufactured in Spain with rigorous quality testing standards
• Does not include spark plug connector (requires separate connector part number 0001594142)
• Compatible with Mercedes-Benz OEM part numbers 0001587203 and 00101

This Bosch ignition coil acts as a transformer, utilizing two coils positioned inside each other to convert low-voltage electrical energy into high-voltage current. The coil briefly stores this energy before releasing it as a high-voltage pulse to the spark plug at the precise moment of ignition. Manufactured to meet or exceed original equipment specifications, this ignition coil ensures reliable performance and long service life. When replacing ignition coils, it is recommended to replace all coils if one fails to maintain consistent engine performance.
