How spark plug quality affects your vehicle’s performance

NGK IMGAEIt may be startling to know that something as small as a spark plug can change the performance of your vehicle by miles. Spark plugs are the device that ignites and power ups the vehicle by providing necessary sparks to light up the fuel. Faulty or sub-standard sparkplugs can cause starting troubles and in longer run can damage the engine permanently due to misfires and over combustion of fuel. They can also adversely affect the mileage of your vehicle. Let’s learn about this in detail to avoid any mishap:


1. Is your vehicle experiencing uneven acceleration?

As discussed before, spark plugs provide the ignition by providing necessary sparks in the combustion cylinders to power the vehicle. If they don’t produce enough spark to burn a particular amount of fuel, you will start experiencing uneven acceleration, low pickup and drop in power also. Meaning when you will hit the accelerator pedal, the increase in speed won’t be smooth. You might also hear a knock sound due to pressure on the engine. This condition is neither good for the engine nor for certain situations when you need quick pick up or acceleration on freeways etc.

If you are facing such a situation, change your spark plugs immediately.


2. Do you have to visit petrol pump too often?

Spark plugs that do not provide regular and continues sparks may cause a lot of problems for the engine in longer run. First, they will ruin the mileage and efficiency of the vehicle by leaving a lot of unburnt fuel in the engine. You will have tank up several times and this unburnt fuel will be a total waste and come out through exhaust and causes pollution in the environment.


3. Can a bad quality spark plug damage the engine parts (like piston or cylinder liner) or electrical gadgets (like sensors or ECM)?

Yes, a bad quality or cheap spark plug can damage the engine parts or electrical gadgets. Because these plugs are not provided with special technical features like Copper Core, Resistor, etc inside it, which are the basic need of engines.


4. Are you facing difficult start-ups?

If you are facing frequent stalls and difficulty while starting the vehicle like long cranking or misfiring the reason behind it could be a bad quality spark plug that is not efficient for the capacity of your vehicle.

Hence always prefer to use good quality and technical features based spark plug to get smooth& hustle free ride/drive.

So, opt for only quality spark plugs and let your vehicle maintain the good performance you desire.

6 Reasons To Change Your Spark Plugs

NGK IMGAE 1Usually, when a vehicle gets ignition troubles, drivers assume that the problem lies with the battery. It might be the case in several situations but, it is just one of the possibilities. The root cause of the problem may lie with the old and wearied out spark plugs. These small auto parts play a big role when it comes to ignition and a keen eye is required to keep them in good shape. Let’s learn the six signs a vehicle provides when it needs a spark plug change:


  1. A faulty or old spark plug can cause misfire problem and starting trouble in the engine. Hence it should be replaced on time. If not replaced within time, it could cause a major and unwanted catastrophe for the engine. Signs of misfiring by spark plugs also include: rough idling, power fluctuations during acceleration, heavy vibration in engine and increase in emissions from the vehicle. Be alert if any of these signs come up.
  2. The spark plugs are responsible for one of the chief tasks of any vehicle, that is, ignition (powering the engine). If your vehicle is experiencing faulty starts, long cranking or frequent stalls, it is time to check the spark plugs. If the vehicle is not starting at all, then the battery may also be the culprit.
  3. If your vehicle is running on wearied out spark plugs, you will observe a sharp drop in mileage. Because of the misfires and non-effective burning of the fuel, your vehicle will consume more fuel then before.
  4. Modern day vehicles when tuned to perfection, hardly make a noticeable sound. If your vehicle is making considerable noise such as, rattling, pinging or knock like, you must get your spark plugs checked.
  5. Normally, when vehicles don’t accelerate quickly enough or provide low pickup, drivers blame it on the clutch plates. It might be a case of faulty spark plugs too. If the vehicle is not getting the right power due to misfires or low ignition, spark plugs must be changed.
  6. Like any other auto part, spark plugs are also a consumable item. Hence it should be replaced periodically or whenever any above mentioned problem occurs. Always prefer to use good quality and technical features based spark plug to get smooth & hustle-free ride/drive.

If you continue to drive on wearied spark plugs, it can cause engine damage in the longer run which will be much costlier for your vehicle. So, if you notice any of such signs in your vehicle, immediately get your spark plugs checked and enjoy a smooth drive wherever you go.
