Mechanics throughout the region know Burleson Nissan has the best selection and price for buying genuine OEM parts. Spark plugs ignite the fuel and air mixture inside your engine's cylinders to generate power. These components must fire thousands of times per minute with precision timing. We carry genuine Nissan spark plugs calibrated specifically for your engine's compression ratio and fuel requirements.

How Spark Plugs Generate Combustion

Spark plugs receive high-voltage electricity from the ignition coil and create an electrical arc across a gap. This spark ignites compressed fuel and air at the precise moment for efficient combustion. The Nissan Quest and Nissan Juke use spark plugs with different heat ranges matched to their engine designs. The ceramic insulator prevents electrical leakage while conducting heat away from the combustion chamber. Metal electrodes form the gap where ignition occurs. These plugs work with your ignition system to ensure every cylinder fires properly.

Why Spark Plugs Deteriorate

Electrodes erode from constant electrical discharge and extreme combustion temperatures. Carbon deposits accumulate on the plug and interfere with spark formation. The gap between electrodes widens as metal erodes, reducing spark intensity. Fuel additives leave residues that coat insulators and reduce effectiveness. Generic plugs often use inferior electrode materials that wear rapidly compared to genuine Nissan components.

When Plugs Need Replacement

Replace plugs according to your maintenance schedule, typically every 30,000 to 100,000 miles based on plug type. Rough idle, hesitation, or misfires indicate worn plugs requiring immediate attention. Decreased fuel economy suggests plugs are no longer igniting fuel efficiently.
