PLUG-SPARK

Premium Ignition Plug for Confident Nissan Performance ⚡

Keep your engine crisp and responsive with an OEM-grade ignition plug designed for strong fire, clean burn, and long life. It restores quick starts, smooth idle, solid mid‑range power, and better fuel economy while protecting the catalytic converter.

Why you need it

Each cylinder depends on a precise spark to ignite the air‑fuel mix. The correct heat range and electrode design prevent fouling, misfire, and knock. Using the proper spec part keeps timing stable and emissions low.

How it works

Your coil charges, then releases energy across the plug gap. The arc forms a flame kernel that rapidly expands, pushing the piston down. A durable core, tight insulator seal, and calibrated gap deliver consistent ignition under load and at high RPM.

What happens if it fails

Hard starts, rough idle, hesitation, poor mileage, sulfur smell, flashing MIL, and loss of power. Long-term misfires can overheat catalysts and stain O2 sensors. Replace as a set to keep bank balance.

Tech notes

Install on a cold engine, verify gap to factory spec, torque correctly, and use a small dab of dielectric grease on the boot. Pair with healthy coils and clean air filter for best results.
