Toyota Sequoia Spark Plugs

Spark plugs are among some of the most important components of your Toyota Sequoia’s powerplant, simply because they ignite the gasoline-and-air mixture thus making the cylinders rotate the crankshaft. Although, just like any other automotive parts, spark plugs wear out over time and greater mileage. There are plenty of tell-tale signs that can inform you of your spark plugs being worn out and requiring replacement. First, spark plugs can simply wear out from plasma arcing. Second, your plugs may begin accumulating much ash and carbon deposits from the fuel.

Third, if your engine seeps oil, spark plugs can get fouled with it while having a thick, gooey coat of crude on them. Fourth, your spark plugs can begin suffering from gap bridging. Fifth, if your engine runs too hot, spark plugs may overheat and glaze over. Sixth, preignition can easily ruin your plugs’ electrodes and grounds. Seventh, detonation can crack ceramic insulators off. And eighth, mechanical damage may occur if your spark plugs were incorrectly installed or have gotten loose in the process. Make sure to check your Toyota Sequoia spark plugs at the automaker-recommended intervals, while performing the necessary maintenance.
