Ignition Coil (COP) for Nissan compact engines ⚡

Why this part is needed

This coil delivers the strong spark your Nissan needs for quick starts, smooth idle, and clean combustion. A healthy spark improves fuel economy, lowers emissions, and keeps the catalytic converter safe. It’s built to handle heat and vibration in the spark plug tube, giving reliable energy to each cylinder .

How it works

This coil-on-plug unit is a small transformer. The ECU charges the primary winding, then cuts power; the collapsing magnetic field induces high voltage in the secondary (often 25–40 kV). That surge jumps the plug gap, igniting the mix. The molded boot seals the tube, while internal suppression cuts electrical noise for stable ECU signals.

What happens if it’s broken ❗

Expect hard starts, rough idle, hesitation, poor fuel economy, and loss of power. The Check Engine Light may appear with misfire codes. Prolonged misfire can overheat the catalytic converter and foul plugs. You may smell fuel in the exhaust, feel shaking at idle, or experience stalling under load.

Replacement tips ✅

• Inspect and replace spark plugs if worn; correct gap matters.
• Clean the plug well, seat the boot fully, use a tiny dab of dielectric grease.
• Swap-test coils between cylinders to confirm the fault follows the unit.
