What Are Spark Plugs?

Spark plugs are a crucial component of your vehicle. These electrical devices produce a spark in internal combustion engines, as the name suggests. This spark ignites the air-fuel mixture in the combustion chamber, thereby starting your engine. 

Like every part in your car, spark plugs wear down over time, so you must replace them approximately every 30,000 miles, though this depends on your specific model. You can consult your owner’s manual or contact our service center for more information.
