OEM Toyota Spark Plugs

Your Toyota needs ignition in order to start. That can't happen without your factory spark plugs. They produce the initial flash of electricity the ignites the air-fuel mix that powers your combustion engine.

How Spark Plugs Work

That flash is generated when the spark plugs send an arc of electricity across a gap between two leads. The gap is calibrated to deliver the ideal sparking needed to fire the air/fuel mist inside the engine cylinder. Ignition leads to your pistons pumping, the crankshaft rotating, and your engine producing the power needed to send you on your way.

When to Replace Your Spark Plugs

Spark plugs can last up to 100,000 miles before needing to be changed out, but it's best to consult your owner's manual to determine how long yours are rated to serve. You want to be sure to change them out before they reach that rated mileage, or you may experience problems like:

• Engine misfires
• Unsteady idling
• Difficulty starting your Toyota
• The "Check Engine" dash light comes on
