Hyundai Elantra Spark Plugs

Such a simple process as creating a spark between the electrodes can be not so easy under certain conditions. High pressure and extreme temperature are negative factors for an electric arc, which ignites the air-fuel mixture inside the combustion chamber. Moreover, the electrodes inevitably wear out and get covered with deposits over time. Contaminated electrodes and bigger spark gap between them affect the energy of the spark and lead to misfiring, bad engine performance, and increased fuel consumption. Fortunately, the plugs are not that expensive, relatively easy to diagnose, and in many cases, the drivers replace them by themselves if necessary.

The Hyundai Elantra is praised for solid build quality, significant fuel economy, smooth ride, and quite a roomy interior. But nevertheless, its owners sometimes report engine misfires; the reasons may lie in various ignition system components including ignition coils, spark plug wires, and spark plugs themselves. The turbocharged GDI engines, which can be found under the hood of some latest versions of the Elantra, are more sensitive to the quality of the plugs. Besides, these small but important components vary by heat rating, so select the right replacement products. High-quality Hyundai Elantra spark plugs are always available in our online store.
