Nissan Murano Spark Plugs

The engine pulling your Nissan Murano runs according to a four-stroke operational cycle. Intake, compression, power, and exhaust sequentially occur inside each of the cylinders, and there is no way to maintain continuous burning, like it was in old steam locomotives. Spark plugs ignite the air-fuel mixture for every cycle, hundreds of times per minute, over and over again. Working this hard, the plugs encounter concurrent extreme pressure and temperature, action of chemically aggressive hydrocarbons, and often get contaminated with carbon deposits. As a result, even though the modern technologies make the lifespan of the plugs fairly long, it remains limited.

The terms, however, vary substantially, and the lifespan depends on the quality of plugs, performance, condition of the engine, grade of fuel, and modes of engine operation. Working in separated cylinders, plugs never fail all at once – they do it gradually, one by one. Beginning to misfire after the cold start, the failing plug results in uneven, erratic idling that typically disappears with the engine warming and rpm increasing. However, if not replaced, the misfiring plug will add some stress on the ignition coil and eventually fail, which badly compromises on fuel efficiency and horsepower. Use our high-quality Nissan Murano spark plugs to ensure the reliable service and durability of replacements.
