Toyota Sienna Spark Plugs

Spark plugs ignite your engine's mix of fuel and oxygen, which it burns for power. Without them, your Toyota Sienna wouldn't start. How a spark plug works is a straightforward process called "spark ignition." First, put your key in your ignition and turn it. An ignition switch activates, and your battery, plus an ignition coil, a starter solenoid, and a starter motor, begin working. Together, they create electricity -- a "spark" -- which the plugs' leads capture and use for the above-mentioned combustion. Then, your engine pistons pump, your crankshaft turns, and the many parts of your minivan get moving.

However, spark plugs don’t last indefinitely. They need to be replaced eventually. Look for the signs that it's time. For one, inspect your plug leads. If they're corroded, or they've widened too far, they may not be capturing charges the way they should. If your engine is misfiring or it has shut down completely, these are two other possible signs. If your spark plugs are broken, though, you should change them right away, as they can seriously damage your engine's cylinders.

Luckily, the spark plugs Toyota makes for its Sienna models are durable enough to millions of ignitions, for up to 100,000 miles. Just don't exceed your owner's manual's recommended mileage limits. In other words, be sure you replace any spark plug close to those limits.
