What Happens to a Car Engine When Using Counterfeit Spark Plugs

SOLO, KOMPAS.com - Spark plugs are a critical component in petrol engines, responsible for igniting the combustion process in the combustion chamber. Despite their small size, these parts play a significant role in vehicle performance. Therefore, using counterfeit spark plugs can cause various engine issues if unnoticed by vehicle owners. Iwan, owner of Iwan Motor Honda Auto Clinic, stated that counterfeit spark plugs pose serious risks to the engine’s ignition system. He explained that, besides reducing engine power, fake spark plugs typically have a shorter lifespan due to low-quality materials, causing the electrodes to wear out faster than genuine ones. ‘Engines may also overheat quickly due to incomplete combustion,’ Iwan said. According to Iwan, the effects of counterfeit spark plugs extend beyond reduced performance. In the long term, this can lead to further vehicle system malfunctions. Therefore, Iwan advised vehicle owners not to be tempted by cheap prices when purchasing spark plugs, especially online. ‘Genuine parts have a set price list. The difference between online and offline prices isn’t significant, so it’s best to know the offline price before buying online,’ he added.
