Distinct Advantage

DENSO Spark Plugs made tough and engineered for excellence.

Once upon a time spark plugs needed to be changed regularly, they wore out, quickly fouled and basically bore the brunt of a particularly harsh engine environment.

As you would expect a lot of things have changed since then, and the fine-tuned, computer-controlled, sensored engines of today are a lot smarter, efficient and precise.

The team at DENSO know cars; from bonnet to boot they have spent seven decades designing, engineering and perfecting car parts – it’s what they do, and they do it darn well.

Spark plugs are one such product they have spent a lot of time testing and refining… thousands and thousands of kilometers of testing; and here’s what they did.

DENSO Made It Tough!

To solve the issue of plug durability and resistance to heat range fluctuations, DENSO developed and patented an Iridium/Rhodium alloy with the highest concentration of Iridium of any spark plug.

It out performs in the most severe engine temperatures resisting oxidation and voltage wear for well over 100,000 kilometers.

DENSO Made It Better

Not content with shear strength, DENSO focused its attention on harnessing the spark. So, in another world-first they made the center electrode super fine and developed a 360- degree laser welding process to hold the tip well and truly in place. This makes their plugs highly ignitable and very stable, which equates to optimised power, better fuel economy and longevity.

DENSO Made It Easy!

Many of the cars on the road today have DENSO parts specifically selected by the car manufacturer as original equipment. Knowing what each engine requires and its tolerances gives DENSO a distinct advantage in the consolidated product range they have developed.

So What’s The Deal With Twin Tip?

DENSO’s revolutionary Twin-Tip design introduces the idea that two tips are better than one. Why? Because the additional tip on the ground electrode results in less obstruction of spark growth, while still maintaining the same gap. Less interference at the spark origin (quenching) means better ignitability for a more powerful and fuel efficient combustion.

Nickel TT Spark Plugs

A true world first, DENSO’s patented Nickel TT Spark Plug features a nickel center and a ‘twin’ protruding ground electrode with a slimmer 1.5mm diameter. This design achieves ignition efficiency closer to DENSO’s premium Iridium ranges without expensive precious metals.

The advantages of Nickel TT include:

  • Improved performance for a lower cost. The Nickel TT Spark Plug range is aimed at drivers who care about value for money and savings on fuel
  • Reduced emissions and improved ignitability leads to less combustion fluctuation, resulting in less fuel consumption and significantly reduced CO, CO2 and HC emissions ess stock, same coverage. The complete Nickel TT Spark Plug range is highly consolidated, comprising of 16 convenient part numbers that cover most of the popular applications within Australia.

Iridium TT Spark Plugs

Unparalleled, DENSO’s Iridium TT spark plugs are the most advanced spark plug on the market.

They feature the world’s smallest 0.4mm Iridium center electrode and 0.7mm needle tip ground electrode, minimising spark interference and maximising ignitability.

By greatly minimising electrode wear, DENSO improved mileage and extended the plug’s useful life. These spark plugs deliver the best all-around performance, exceptional fuel economy and extraordinary endurance. In fact, they’re designed to last 100,000 kilometers; which makes these plugs suited to the rigour of long distance and heavy use driving.

DENSO offers their customers the most advanced spark plugs on the market and coverage for most makes and models on the road today. To reap the reward all you need to do is make the switch.
