SUPPORTED MODELS (2006-2015 Lexus IS250)
A genuine Toyota spark plug is a spark plug that is manufactured by Toyota or one of its approved suppliers and is designed
specifically for use in Toyota vehicles. These spark plugs are engineered to meet the specific performance and reliability
requirements of Toyota engines, and are typically considered to be of higher quality and longer lasting than aftermarket
spark plugs. When purchasing a spark plug for a Toyota vehicle, it is recommended to use a genuine Toyota spark plug to
ensure proper performance and to avoid potential damage to the engine. A spark plug in a car is responsible for providing
the spark that ignites the fuel and air mixture in the engine’s cylinders. It is a small electrical component that is located in
the cylinder head and screwed into the engine block. The spark plug consists of a central electrode that is surrounded by a
metal casing, and a ground electrode that is connected to the engine block.
When the engine is running, an electrical current flows from the ignition coil, through the spark plug wire, and to the spark
plug. The current flows across the gap between the central and ground electrodes, creating a spark. This spark ignites the
fuel and air mixture in the cylinder, causing the engine to run.
It’s important to note that Spark plugs have a limited lifespan and need to be changed periodically, depending on the make
and model of your vehicle, manufacturer recommendations and the condition of your engine.
When the spark plug wears out, it can cause the engine to misfire, lose power, or have difficulty starting. It’s also important
to note that poor fuel economy, poor performance, and a decrease in power can be caused by malfunctioning spark plugs.
