Denso Platinum TT Spark Plug – PKH20TT Long

Description

The Denso Platinum TT is an advanced aftermarket spark plug engineered with Denso’s signature Twin-Tip (TT) technology. Designed to bridge the performance gap between standard copper plugs and expensive precious-metal variants, the PKH20TT utilizes a combination of a platinum center electrode and a titanium-enhanced ground electrode to optimize combustion efficiency, throttle response, and fuel economy.

Key Features & Benefits

• Twin-Tip (TT) Technology: Features a reduced 1.1mm platinum-tipped center electrode paired with a titanium-enhanced 1.1mm ground electrode. This minimal profile lessens electrical “quenching,” allowing a larger, hotter flame kernel to grow more quickly.
• Improved Combustion & Efficiency: Faster flame propagation results in more complete fuel burn, translating to smoother acceleration, better fuel economy, and quicker cold starts.
• Enhanced Durability: The combination of platinum and titanium alloys resists spark erosion and high-temperature gap widening significantly better than standard nickel plugs.
• Gas-Tight Seal & Construction: Utilizes a copper-glass seal to bond the center electrode and insulator, alongside a purified alumina powder insulator that offers exceptional dielectric strength and thermal conductivity.
• Anti-Seize Thread Rolling: Features machine-rolled threads that prevent cross-threading and protect aluminum or cast-iron cylinder head threads during installation.
