Original Lexus Spark Plugs

Spark plugs for your Lexus play a huge part in the engine's combustion process. Because your vehicle requires a sequence of fuel, air, and electricity to start, spark plugs are what kicks off the start of your engine. Here's how it works.

How a Spark Plug Works

Spark plugs are made from a combination of materials. They are small parts that fit into the top of your engine's cylinder head. They have a ceramic housing that surrounds a nickel or copper rod, which is what conducts the charge, or "spark" which ignites the mixture of air and fuel. Spark plugs are covered with a rubber protective casing, and are usually easy to find and replace.

Since engine parts tend to last only a few years due to high heat and constant vibration beneath the hood, spark plugs usually require an exchange between 80,000 and 100,000 miles. Signs that your spark plugs are failing are:

• Check engine light
• Engine starting trouble
• Engine misfires
• Lack of acceleration
• Drop in fuel efficiency
