Common Applications and Problem Resolution

• Replacement for faulty or worn ignition coils causing misfires
• Restores proper spark delivery in distributorless ignition systems
• Eliminates rough idling and engine hesitation related to coil failure
• Addresses starting difficulties due to weak or no spark
• Prevents engine stalling caused by inconsistent ignition voltage

Installation Notes and Tips

Installation of the NGK DIS Ignition Coil 48780 requires disconnecting the battery and removing the old coil carefully to avoid damage to wiring connectors. Ensure the blade terminals and connector genders match the vehicle’s harness for a secure fit. Since this coil does not include a mounting bracket, reuse the existing bracket or mounting hardware. Verify all electrical connections are tight and free of corrosion before reassembly. After installation, perform a test start to confirm proper ignition function.
