Platinum and Titanium

Platinum is one of the rarest metals on earth and is an excellent material for spark plugs, thanks to its superior resistance to corrosion and erosion in harsh environments. Sometimes called the "space age metal", Titanium has a low density and is a strong, lustrous, corrosion-resistant material ideal for extending the life and performance of spark plugs.

Platinum and Titanium Combination: Platinum on the center electrodes and Titanium-enhanced alloy on the ground electrode increases durability and minimizes tip erosion.

The DENSO Difference

The TT concept originated from DENSO's latest OE spark plug technology, the Super Ignition Plug, or SIP. Until recently, this original equipment iridium Twin-Tip design could only be found in today's most technologically advanced automobiles. Now, DENSO is offering this cutting-edge technology in a brand new Platinum/Titanium design customized for today's value- minded automotive enthusiasts.

Twin-Tip Technology

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.

High Durability

DENSO's revolutionary Twin-Tip design is a combination of highly durable precious metals - Platinum and Titanium. The center electrode is created using an extremely durable Platinum alloy that allows for the reduction of the tip size to 1.1 mm in diameter, while maintaining the life of the plug. The Titanium-enhanced alloy on the ground electrode also increases durability, which is critical to minimize tip erosion and achieve the new Twin-Tip design.

Performance & Value

Superior ignitability of the DENSO Platinum TT means more efficient combustion, which yields better engine performance in terms of power and fuel economy. Better mileage, more power, and faster starts, all while reducing carbon emissions are what places the Platinum TT heads above the competition. Top performance, total value.

Save On Fuel

With the fluctuating cost of gas nowadays, it's nice to get ultimate performance in a spark plug that isn't too expensive and efficiently burns the gas you buy. The DENSO Platinum TT™ is remarkable in that it gives you absolute leading-edge technology and remarkable economy. That's the benefit of buying the Platinum TT. Who couldn't use a few more dollars in their pocket?

Why should I use the Platinum TT®?

Our customers choose the Platinum TT to achieve better fuel economy, durability and reduce their carbon emissions. They also appreciate the durability of the Platinum TT, resulting in a longer lifespan coupled with enhanced performance..

What features make the Platinum TT a superior spark plug?

DENSO's revolutionary Twin-Tip design uses the latest OE technology in combination with Platinum and Titanium, two highly durable precious metals. The center electrode is created using an extremely durable Platinum alloy that allows for the reduction of the tip size to 1.1mm in diameter, to increase performance, while still maintaining plug life. The Titanium-enhanced alloy on the ground electrode further increases durability, which is critical to minimize tip erosion and allow the high-performing Twin-Tip design to function over the long-term. These design features combine to offer better performance through reduced quenching which results in a larger spark and faster flame propagation for a more complete combustion and maximized fuel efficiency.

What makes the Platinum TT stand out above the competition?

Superior ignitability of the DENSO Platinum TT means more efficient combustion, which yields better engine performance in terms of power and fuel economy. Better mileage, more power and faster starts, all while reducing carbon emissions are what places the Platinum TT Spark Plug heads above the competition.
