2. What are three reasons to upgrade?
3. Why buy the spark plugs SILZKR7E11 by NGK Spark Plugs?

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. You need as many spark plugs for your engine as you have cylinders. Therefore, a 4Cyl 2.4L engine like that of your 2015-18 Hyundai Sonata requires the same number of spark plugs as there are cylinders.

What are Three Reasons to Upgrade?

Lower Maintenance Costs

It will cost you $12.06 to acquire one of the spark plugs SILZKR7E11, so to change all the spark plugs of your 2015-18 Hyundai Sonata, you will expend approximately $30 on spark plugs alone. The generic replacements are cheaper ($3 a piece or less), but you will have to replace 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

With the first-rate materials and innovative and more effective design, the spark plugs SILZKR7E11 require less charge to deliver sparks into the engine cylinders. As a result, current tends to flow through the ignition coil primaries of these plugs for more prolonged, enhancing performance and increase fuel economy.

Improved Consistency in the Winter

Cold temperatures can decrease the performance and efficiency of your car’s ignition system, and at times, can even cause your stock spark plugs to foul. When it gets cold, your battery may not provide enough electricity to cause a spark that can bridge the gap between the center electrode tip and the taper cut side electrode. The spark plugs SILZKR7E11 are designed with materials that attain better conductivity, and they also have better gapping between the electrodes. Henceforth, you can count on these spark plugs to deliver focused sparks with greater consistency in the winter.
