DENSO pioneered the use of platinum in spark plug manufacturing. To maximize the longevity and enhance the durability of the spark plug, DENSO applied platinum to both the center and ground electrodes. Platinum offers superior resistance to erosion and corrosion enabling DENSO to create a spark plug capable of consistent performance.

• Superior ignitability of the DENSO Platinum TT means more efficient combustion, which yields better engine power and fuel economy.
• Better mileage, more power, and faster starts, all while reducing carbon emissions.
• Less interference at the spark origin means better ignitability for a more powerful and fuel-efficient combustion.
• Additional tip on the ground electrode results in less obstruction of spark growth, while still maintaining the same gap.
• Titanium-enhanced alloy ground electrode and minimum-quench electrode design.
