Technical Specifications

Applications and Vehicle Compatibility

The Bosch 0221503487 ignition coil is engineered to meet the demands of a broad spectrum of engines. Its versatility makes it suitable for:

• Small displacement gasoline engines (1.0–1.5 L) found in compact cars and hatchbacks.
• Mid‑size engines (2.0–3.0 L) used in sedans, coupes, and SUVs.
• Performance variants of Ford models such as the Fiesta, Mondeo, and other vehicles that utilize Bosch’s single‑coil ignition architecture.
• Aftermarket performance builds where a reliable spark source is critical for maintaining engine efficiency and power output.

Installation Guidelines

1. Safety First: Disconnect the vehicle’s battery to prevent accidental electrical discharge during installation.
2. Remove Old Coil: Carefully detach the existing ignition coil by loosening the mounting bolts and disconnecting the spark plug wire. Note the orientation of the coil for correct reinstallation.
3. Position New Coil: Align the Bosch 0221503487 with the engine block’s mounting points, ensuring that the connector pins line up precisely with the terminal posts.
4. Tighten Securely: Use a torque wrench to tighten the mounting bolts to the manufacturer’s specified torque (typically around 10–12 Nm). Over‑tightening can damage the coil housing or engine block.
5. Reconnect Spark Plug Wire: Attach the spark plug wire to the new coil, ensuring a snug fit. Verify that the wire is not pinched or twisted.
6. Recheck Connections: Inspect all electrical connections for proper seating and secure fastening.
7. Reconnect Battery: Restore power to the vehicle’s electrical system.
8. Test Run: Start the engine and observe smooth operation. Listen for any irregularities such as misfires or rough idling, which may indicate a faulty installation or compatibility issue.

Maintenance Tips

• Regularly inspect spark plug wires for signs of wear, cracking, or insulation damage. Replace them if any abnormalities are detected.
• Keep the engine bay clean and free from excessive oil or coolant leaks that could compromise coil integrity.
• Perform periodic checks on the ignition system’s overall health using a diagnostic scan tool to detect potential issues early.
