The engine in your Nissan relies on Direct Ignition Coils to start. Spark plugs require thousands of volts to generate the spark needed for ignition—significantly more than the 12 volts your vehicle’s battery supplies. Ignition coils increase this voltage from the battery and deliver it to the spark plugs, enabling your engine to start. Without functioning Direct Ignition Coils, your Nissan won’t operate.

• Essential for Starting: Direct Ignition Coils are vital for your Nissan’s engine to start, as spark plugs need thousands of volts—well beyond the 12 volts from the battery—to ignite.
• Voltage Boost: Ignition coils take the battery’s voltage, boost it, and transfer it to the spark plugs, creating the spark needed for ignition.
• Types of Ignition Systems: In direct (coil-on-plug) ignition systems, each spark plug generally has its own ignition coil, although some designs use one coil for two plugs.
• Engine Size Determines Coil Count: Your Nissan’s engine size, outlined in your owner’s manual, dictates the number of spark plugs and Direct Ignition Coils it requires.
• Lifespan and Maintenance: Direct Ignition Coils typically last about 100,000 miles, but frequent driving or worn spark plugs can increase wear.
• Signs of a Failing Coil: Indicators of a faulty Direct Ignition Coil include difficulty starting, a check engine light, backfiring, or engine stalling.
• Replacement Requirements: Damaged ignition coils cannot be repaired and must be replaced. You can perform this replacement at home or visit a service center for professional help.
• Choose Genuine Parts: For reliability and a precise fit, always select genuine OEM parts when replacing your Direct Ignition Coils.
