Lexus OEM Spark Plugs

Buyer's Guide to Lexus Spark Plugs

Your Lexus car or SUV requires ignition in order to start at your command. That happens in large part thanks to the spark plugs, which provide the initial flash that ignites the mixture of air and fuel inside the engine.

How Lexus Spark Plugs Work

That flash is generated when the spark plugs fire an arc of electricity across a gap between the two leads in the plug's head. Those gaps are calibrated to provide the ideal spark needed to kindle the mixture inside the combustion chamber, leading to your engine purring to life.

How to Recognize Failing Spark Plugs

Eventually, though, your spark plugs will begin to become less effective. Maybe they've become corroded. Perhaps the gaps have grown too wide to produce an effective spark. Signs of problems include:

• Your engine begins to misfire
• You have trouble starting your vehicle
• The engine idles rougher than usual

There's one other sign of trouble, and that's when your "Check Engine" dash light comes on. However, this is a pretty common alert, and one that can be triggered by many different issues. You'll want to connect a code reader to determine whether your spark plugs are the source of the alert, rather than something else.
