Buying guide for spark plugs

The guiding factors behind buying spark plugs are listed below.

The symptoms

Before you go out to buy a new spark plug, you need to check out some of the symptoms that tell you that the existing one needs replacement. A misfiring spark plug will produce unusual noises that will sound like rattling or knocking. The car might have trouble starting up and it can be disjointed and jerky. A faulty spark plug will also result in a sluggish and disjointed ride and reduction in acceleration even when you are pressing the pedal. It will also reduce the fuel economy of the car, thereby draining you out of precious fuel.

The information

While buying a spark plug, you need to have the right information about the make and model of your car along with the details about the engine. This include the type of engine, number of cylinders and the method of transmission. You also need to know about the engine volume displacement and the type of fuel injection system the car has. Other than that you should also know about the space that there should be between the centre and side electrodes of each spark plug called the spark gap and the part number of the plug.

The material

Spark plugs can be of many types and the major types include copper core, single and double platinum and iridium plugs. Copper is the affordable option and fits older models very well. Platinum plugs are long-lasting and the double platinum ones last even longer. Iridium plugs are long lasting and also have a high firing efficiency while being costlier on the other hand. They also fire at lower temperatures and are an upgrade over the standard platinum ones. The type you choose will depend on your requirements based on the owner’s manual and the budget.

The quality

There are cheaper spark plugs available in the market but it is best not to invest in such a product. That will only result in the fast wearing out of the plug and frequent replacements, which will affect your car’s overall performance. A quality spark plug from a reputed brand will serve you for years and will also keep the engine of the car in a good condition. Try to select from the reputed brands which have years of manufacturing experience behind them.
