6 PCS *NEW* -- DENSO #4504 PLATINUM T T Spark Plugs -- PK20TT

Product Description

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.

Features

• DENSOs 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 1.1mm 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
• Superior ignitability of the DENSO Platinum TT means more efficient combustion, which yields better engine performance in terms of power and fuel economy.
