The patented DENSO Platinum TT Spark Plug has a twin-tip design to improve ignitability and extend reliability. Until recently, this twin-tip design could only be found in the most technologically advanced automobiles. But now DENSO is offering this cutting-edge technology in a platinum-titanium design. Conventional platinum plugs use platinum for only the center electrode, while the DENSO Platinum TT Spark Plug features platinum on the center electrode and a titanium-enhanced alloy on the ground electrode for increased durability and minimized tip erosion. Both precious metals fight corrosion and erosion, ensuring superior spark performance and maximum spark plug life capable of extended operation in excess of 60,000 miles. In addition, the secondary tip on the ground electrode results in less obstruction of spark growth, while still maintaining the same gap. With this in mind, if your vehicle exhibits bad spark plug symptoms including slow acceleration, poor fuel economy, or engine misfires, consider DENSO for your performance spark plug replacement.
