Your Toyota needs ignition in order to start on demand. That doesn't happen without the factory spark plugs doing their job. They create the initial flash that ignites the oxygen/fuel mixture your combustion engine runs on. The spark plugs achieve this by creating an arc of electricity that jumps across a gap between the two leads. Those gaps are optimally placed to deliver the ideal sparking required by your engine. Once your pistons begin pumping and the crankshaft kicks into action, you're off on an adventure. Even the high-quality Toyota spark plugs that came with your car or SUV can eventually start to fail, however.
When to Change Your Toyota Spark Plugs
It's easy to assume that your alternator is at fault when you begin to experience engine misfires and shutdowns. Take a moment and assess your spark plugs, though. The gaps may have slowly widened to the point where the spark has grown too weak for your engine's needs. Maybe they've corroded. While modern spark plugs can offer up to 100,000 miles of service, some need changing sooner. Don't risk bad or broken spark plugs causing lasting engine damage. Check your owner's manual to determine the right time to change yours so that you can replace them before their maximum mileage rating elapses. Then make sure to use the spark plugs that work best for your model. Those would be original Toyota spark plugs. We have a great selection in stock and ready to ship.
