Keep Combustion Consistent With INFINITI Spark Plugs
Spark plugs ignite the air-fuel mixture inside the engine cylinders. This process occurs repeatedly during every drive. At INFINITI of Akron, spark plug condition is often reviewed during engine service discussions. Wear develops naturally over time.
What Spark Plugs Do
Spark plugs generate an electrical spark that starts combustion. Consistent firing supports smooth engine operation. INFINITI vehicles such as the Q50 and QX80 use plugs specified for engine design.
Why Spark Plugs Wear Out
Electrodes erode from heat and electrical discharge. Deposits may build up from fuel combustion. Mileage and driving habits influence lifespan.
OEM Spark Plug Selection
