NGK SPARK PLUG IMR8C-9H 3653 NG3653

NGK Iridium Racing IX Spark Plug - IMR8C-9H [3653]

Experience enhanced ignition performance with the NGK Iridium Racing IX Spark Plug. Engineered with advanced iridium technology, this spark plug features an ultra-fine 0.6 mm diameter center electrode, significantly reducing voltage requirements and prolonging the life of your ignition system. The tapered ground electrode is designed to promote stronger flame core growth, leading to improved acceleration and better fuel efficiency.

Key Features:

• Advanced Iridium Technology: Features a 25% smaller electrode compared to platinum and is 1/4 the size of conventional nickel electrodes.
• Ultra-Fine Center Electrode: The 0.6 mm diameter reduces voltage needs and extends ignition system durability.
• Enhanced Flame Core: A tapered ground electrode boosts flame core expansion for superior ignition performance.
• Improved Fuel Efficiency and Acceleration: Optimized design contributes to noticeable gains in engine response.
• Anti-Corrosion Properties: Enhanced metal shell plating provides superior resistance to corrosion.
