DENSO PREMIUM CLASS IRIDIUM SPARK PLUG

Denso's Premium Class Iridium Spark Plugs is fast becoming the standard for today's high-tech engines. Employing a revolutionary 360 degrees laser welding process, Denso has created a spark plug unlike anything on the market today. Designed for durability under the most extreme conditions. Denso's patented Iridium alloy is 6 times harder and 8 times stronger than conventional platinum and can handle temperatures in excess of 4,000 degrees Fahrenheit.

Specification:

• 14 mm thread size
• 18 mm reach
• 0.63 in. hex size
• 0.04 in. gap size
• Tapered seat style
• Resistor plug type
• 0.4 mm iridium center electrode
• Tapered cut U-groove ground electrode
• Removable terminal
• Heat range 16

Features:

• Designed with heavy duty insulator that provides unparalleled dielectric strength and thermal conductivity under extreme temperatures
• Five-rib design prevents flashover while decreasing voltage loss
• Copper glass seal bonds the center electrode and insulator together for a gas-tight seal
• Platinum center electrode utilizes platinum to shrink the surface area of the center electrode tip for maximum firing performance and minimum voltage requirements
• Platinum ground electrode resists gas and electrical erosion and corrosion extending service intervals to 60,000 miles
