Support Reliable Combustion With INFINITI Spark Plugs
Spark plugs ignite the air and fuel mixture inside engine cylinders. This action occurs repeatedly during normal driving. At Modern INFINITI of Winston-Salem, spark plug condition is often discussed during engine service visits. Wear develops naturally with mileage.
What Spark Plugs Do
Spark plugs create an electrical spark that initiates combustion. Consistent ignition supports smooth engine operation. INFINITI vehicles such as the Q50 and QX80 use plugs specified for precise engine requirements.
Why Spark Plugs Wear Out
Electrodes erode from repeated electrical discharge. Carbon deposits may build up over time. Driving habits and fuel quality influence service intervals.
OEM Spark Plug Benefits
Genuine INFINITI spark plugs are manufactured to factory heat range and gap specifications. Lower-priced aftermarket plugs may vary slightly in construction. Proper ignition also supports the ignition system. Modern INFINITI of Winston-Salem offers OEM spark plugs designed for consistent engine response.
