Spark Plugs

Spark plugs create a spark that ignites the combination of fuel and air in the internal combustion engine. This is an important step in powering a vehicle. Over time, spark plugs wear and can cause your engine to misfire or run poorly. The fuel efficiency of your vehicle can also suffer when your spark plugs are not working optimally; and your car's emissions can increase. Don't risk poor engine performance. Replace failing spark plugs with high quality parts from Sears. For even more power and superior performance of your ignition system, see our selection of performance spark plugs.
