Installation Guide

1. Disconnect Battery: For safety, remove the negative battery terminal before working on the ignition system.
2. Remove Old Coil: Locate the existing coil in the engine bay. Detach the electrical connector and unscrew the mounting bolts that secure the coil to the cylinder head or intake manifold.
3. Position New Coil: Align the new U5054 (48201) coil with the mounting holes. Ensure the connector’s orientation matches the original placement to avoid misalignment.
4. Screw in Place: Tighten the mounting bolts to the manufacturer’s specified torque setting, typically around 10–12 Nm for most Nissan engines.
5. Reconnect Electrical Connector: Plug the coil’s connector into the ECU or distributor harness, ensuring a snug fit.
6. Reattach Battery and Test: Reconnect the battery terminal. Start the engine to verify smooth operation; listen for any misfires or irregular idle patterns.

Performance Benefits

• Improved Fuel Efficiency: A consistent spark reduces incomplete combustion, leading to better mileage over time.
• Enhanced Engine Longevity: By delivering a reliable spark, the coil minimizes wear on pistons and valves caused by misfires.
• Reduced Emissions: Efficient ignition lowers unburned hydrocarbons in exhaust gases, helping vehicles meet stricter emission standards.
• Consistent Power Delivery: Drivers experience smoother acceleration and reduced hesitation during throttle changes.
