Bosch 0221604022 Direct Ignition Coil Coil-On-Plug

The Bosch 0221604022 is a high-performance direct ignition coil engineered to deliver reliable spark energy for optimal engine performance. This compact coil-on-plug design mounts directly over the spark plug, eliminating the need for spark plug wires and ensuring efficient energy transfer.

Key Features:

• Compact coil-on-plug configuration for direct mounting
• Generates approximately 30,000 volts from the vehicle's 12-volt electrical system
• Three-terminal SAE connector with female gender for secure electrical connection
• Electronic ignition type with 14-volt operating voltage
• Single bolt-in mounting hole for secure installation
• Oil-free design for maintenance-free operation

This ignition coil transforms low battery voltage into the high voltage necessary to create a strong spark at the spark plugs, igniting the air-fuel mixture for smooth engine operation. Bosch original equipment quality ensures proper ignition voltage, long-lasting spark performance, improved fuel economy, and reduced exhaust emissions. Replaces OEM part numbers LR010687 and AJ811378.

Common Failure Symptoms: Engine misfires, difficult starting, rough idling, decreased fuel efficiency, and check engine light illumination with codes P0300, P0301, P0302, or P0316.
