With relentless dedication to quality, reliability and state of the art manufacturing, NGK spark plugs are to be trusted in any application. NGK glow plugs are at the forefront of technological innovations when it comes to diesel engine technology. Maintaining optimum starting capabilities and excellent post-glow function to promote clean combustion and lower toxic emissions, NGK glow plugs are a no-brainer when servicing your diesel engine. Whether you drive a modern diesel European hatchback or a tough, modified off-road diesel trail blazer, NGK glow plugs are all manufactured to the same standard with state of the art techniques, quality assurance and reliability.
Spark plugs are one of the most important components of your engine to ensure correct engine operation and smooth, efficient running. The majority of misfire issues and other hesitations can be traced to issues with the engine's spark so it's important to keep on top of spark plug health in order to eliminate one of the key factors to potential misfires. Without fresh spark plugs that are correctly gapped, correctly installed and in good health without damage, some other issues beyond misfires you can notice are poor fuel economy, lack of acceleration or general performance, rough idling or hard starting which can all be traced back to fouled, dirty or damaged spark plugs. Using a spark plug socket, you can remove your spark plugs to examine for any signs of damage or fouling. It's important to look for oil or fuel deposits, cracks, splits, thread damage or missing material from the spark plug body. If you notice any of these issues, it's time to invest in a fresh set of NGK spark plugs for your car.
Unlike petrol engines, diesel engines do not require a spark to ignite the fuel as it is automatically ignited by the high temperatures created by substantially higher cylinder pressures than that of a petrol engine. When the engine is cold, these temperatures are not always achieved and the starting processes needs to be assisted by the glow plugs which heat the air-fuel mixture when cold starting. While some modern vehicles will display an engine light when a glow plug is faulty, this is not the case with older machines. The typical issue categorises a bad glow plug is hard starting or even not starting at all in cold conditions. If you notice misfiring or rough idling when the engine is warming up, it can be a result of the engine starting without the desired cylinder temperature which is also indicative of a failing glow plug. White smoke when starting or cranking is the result of diesel fuel being expelled through the exhaust which has not been given the opportunity to burn. This can be a result of low cylinder temperatures caused by failing spark plugs.
