Spark Plugs Video
The spark plug ignites a compressed mixture of fuel and air. This causes an explosion which causes the pistons to move up and down. The power generated from these explosions is ultimately what powers your car, truck, or SUV.
Spark plugs need to be changed on regular intervals. Each automaker has a recommended replacement interval. If your car is idling rough, losing fuel economy, misfiring, or if you are unsure when your spark plugs need to be replaced, call George's Sierra Shell in Fontana at 909-822-3402, and ask our team of experts.
