Technical Specifications

Installation Guide

1. Safety First: Disconnect the battery to prevent accidental spark or electrical shock.
2. Remove Old Coil: Detach the existing ignition coil by loosening the mounting bolts and carefully pulling it away from the engine block. Note the orientation of the coil for correct placement.
3. Prepare the Engine Block: Clean the mounting surface with a solvent to remove oil, dirt, or old gasket material. Ensure the surface is flat and dry.
4. Mount the New Coil: Place the Bosch 0221504800 onto the prepared surface, aligning it with the mounting holes. Secure it using the supplied bolts and torque them to the manufacturer’s specification (typically 10–12 Nm).
5. Connect Spark Plug Lead: Attach the insulated lead to the coil’s output terminal. Tighten the connection securely but avoid over‑tightening, which could damage the insulation.
6. Reconnect Battery and Test: Reconnect the battery terminals. Start the engine and observe for smooth operation. If the engine misfires or stalls, double‑check all connections and torque settings.

Performance Benefits

• Improved Combustion: The high‑voltage spark ensures complete fuel–air mixture ignition, reducing unburnt hydrocarbons.
• Enhanced Fuel Economy: Efficient combustion translates to lower fuel consumption and better mileage.
• Reduced Emissions: Consistent spark timing helps meet stringent emission standards by minimizing incomplete combustion products.
• Reliability Under Stress: The coil’s robust construction tolerates high engine temperatures and vibration, providing dependable performance over time.

Compatibility Matrix

The Bosch 0221504800 is engineered to fit a broad spectrum of vehicles. Below is a concise compatibility overview for major OEMs:

Maintenance Tips

• Inspect the coil’s insulation regularly for cracks or wear. Replace if any damage is found.
• Keep the mounting area clean to prevent corrosion that could affect electrical contact.
• Use a torque wrench when reinstalling bolts to avoid over‑tightening, which can deform the coil housing.
• Monitor engine performance; sudden loss of power or rough idling may indicate a failing ignition coil.
