Spark Plugs

Toyota Genuine Parts - Spark Plugs

The spark plug is one of the smallest and cheapest components in an engine, yet it is responsible for actually making the engine operate. Thousands of times every minute, the spark plug ignites the fuel and air mixture which propels the engine's cylinders to drive the car.

Toyota Genuine Spark Plugs feature a unique U-groove ground electrode which means it creates a bigger and brighter spark for better fuel efficiency, faster response and lower gas emissions.

A brighter spark for better fuel efficiency and faster response

At first glance, all spark plugs look pretty much the same. However, there are many differences between spark plugs that can make enormous differences to the way your engine performs. In fact, non-genuine spark plugs can not only reduce performance, they can also increase the chances of damage to your engine.

A strong case for Toyota Genuine

The case or housing around the internal spark plug components is vital to the stable performance and long life of the plug. The precise construction and quality materials of a Toyota Genuine Spark Plug housing ensures a high rate of thermal conduction which prevents the plugs from running 'too hot' or 'too cold' and causing engine misfires or pre-ignition (which may also cause engine damage).

Precision construction delivers precision performance

Spark plugs must operate within a precise heat range. If they work outside that range, the plug will not operate at optimum efficiency - resulting in poor starting, reduced performance under load, and increased fuel consumption. Equally important is the resistor located between the centre electrode and the centre axis, which prevents interference with onboard electronics such as your radio. So, if your radio is full of static, chances are you've got spark plugs that are impairing your engine's performance.

How to tell if you need new spark plugs

Common signs that your spark plugs need to be replaced include difficult starting, unstable running, engine misfires, loss of performance and increased fuel consumption.
