If you are a long distance or heavy-use driver, ask your Natrad technician to install Denso Iridium TT spark plugs. These spark plugs are designed to provide higher mileage and better performance than standard spark plugs.
For the environmentally conscious driver needing a more economical solution, we supply Nickel TT spark plugs. This less expensive design does not require precious metal electrodes, yet still reduces CO2 emissions and improves fuel economy.
If your spark plugs fail too often, your Natrad technician may recommend using a spark plug with a higher thermal value. It may also pay to tune the engine, adjust the carburettor, and of course, have your cooling system checked at the same time.

A spark plug sits in the engine head of your car. It provides the spark that ignites the fuel, creating the combustion that drives the car. If it fails, your car may not start.
Denso spark plugs are made from high-quality materials and offer the smallest centre electrode diameter. This means that performance and fuel economy can be improved. As a Denso spark plugs Australian supplier, we stock a wide range of the best spark plugs to suit both your performance requirements and your budget.
Signs that your spark plugs may need replacing include poor starting, less power, rough idling or poor fuel economy.
If you’ve increased your engine power output, weekly mileage, or the environmental operating conditions of the car, it pays to check that the spark plug is still suitable. A Natrad technician can advise you on the best spark plug for your vehicle.
Spark plug lifespan can vary depending on your vehicle’s operating conditions and engine health. When it’s hotter, there’s a higher load on the engine, and spark plugs fail sooner. If your car is due for service before summer, this is an excellent opportunity to get the spark plugs checked and upgraded if required.
