What is a Spark Plug?

A spark plug is a vital part of your car’s ignition system. It introduces a spark of electricity into an engine’s combustion chamber, resulting in the ignition of the air-and-fuel mixture therein and the power generation to start up the car. The NGK Spark Plugs SILZKR6B11 is fashioned to deliver these electric charges more reliably [dependably, consistently] and efficiently than your stock spark plugs.

Increased Performance

These spark plugs feature 98% copper core and tips that are made from laser iridium. They also feature tapered-cut, spe ground electrodes that promote ignitability while reducing quenching. As a result, these spark plugs provide more consistent sparks to their tips, causing better combustion of the air and fuel in the cylinders, and consequently, more excellent performance.

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 produce enough electricity to cause a spark that can bridge the gap between the center electrode tip and the spe side electrode. The spark plugs SILZKR6B11 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.
