What is a Spark Plug?

A spark plug helps to start and control the combustion of air and fuel in your engine’s combustion chambers. It relays sparks or electric charges from the car’s ignition system into an engine combustion chamber, igniting the fuel/air mixture. There is a spark plug for each cylinder of your engine. Therefore, a 4Cyl 2.4L engine like that of your 1999-05 Hyundai Sonata needs the same number of spark plugs as there are cylinders.

What are Three Reasons to Upgrade?

Lower Maintenance Costs

It will cost you $9.48 to buy one of the spark plugs PGR5C-11, so to change all the spark plugs of your 1999-05 Hyundai Sonata, you will expend approximately $30 on spark plugs alone. The generic replacements are lower-priced ($3 a piece or less), but you will have to change them every 30,000 to 50,000 miles. On the other hand, with these NGK spark plugs, you will have longer replacement intervals of [between 60,000 to 100,000 miles] ( Therefore, when using generic spark plugs, you will end more on spark plug replacement service in the long run.

Increased Performance

These spark plugs by NGK Spark Plugs are made with 98% copper core and single platinum tips to enhance heat dissipation. They also feature tapered-cut, standard ground electrodes that promote ignitability while decreasing quenching. As a result, these spark plugs provide more reliable sparks to their tips, resulting in improved combustion of the air and fuel in the cylinders, and consequently, more excellent performance.

Improved Consistency in the Winter

The winter season’s low temperatures can put a damper on the chemical processes in your car’s battery, causing it not to hold a charge as long as it does in warmer weather. As a result, your spark plugs may not receive as much electric charge as they would otherwise get from the battery to start the car. The good thing is that the spark plugs PGR5C-11 do not need as much charge as generic spark plugs to provide focused sparks. So, you are more assured of being able to start the 4Cyl 2.4L engine of your 1999-05 Hyundai Sonata in the winter with these spark plugs.
