Denso Iridium TT Spark Plug – IXEH20TT Long

Description

The Denso Iridium TT  is one of the most advanced high-performance spark plugs on the market. Combining Denso’s ultra-fine 0.4mm iridium center electrode with a patented 0.7mm needle-shaped titanium ground electrode, the Iridium TT is engineered to deliver maximum spark energy, superior ignitability, exceptional fuel efficiency, and a service life that routinely reaches up to 100,000 miles.

Key Features & Benefits.

• Industry-Leading Fine Wire Design: Features the world’s smallest 0.4mm iridium center electrode matched with a 0.7mm titanium ground electrode. This twin-needle configuration drastically reduces electrical “quenching,” allowing a massive, highly concentrated flame kernel to expand rapidly.
• Maximum Combustion Efficiency: The ultra-fine spark points focus electrical energy, leading to a more complete and efficient air-fuel burn. This translates to sharper throttle response, smoother idling, and optimized fuel economy.
• Exceptional Longevity: Pure iridium is six times harder and eight times stronger than platinum, offering extreme resistance to spark gap erosion, high combustion pressures, and thermal breakdown over tens of thousands of miles.
• Anti-Fouling & Self-Cleaning: The wide thermal gap between the center electrode tip and the insulator nose prevents carbon buildup and fuel fouling during stop-and-go driving.
• Precision Construction: Utilizes a copper-glass seal for supreme gas-tight sealing and thermal conductivity, combined with rolled threads to protect cylinder head threads during installation.
