Spark plug is one of the parts that is smallest in size and low in price 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. At first glance all spark plugs look the same. However, there are many differences between spark plugs which make enormous differences to the way your engine performs. 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. Some non-genuine spark plugs can not only reduce performance, they can also increase the chances of damage to your engine by failing to provide an optimal fuel firing environment.
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. 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 (That can cause engine damage). 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 center electrode and the center 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.
