DENSO Iridium Racing Spark Plug

The DENSO Iridium Racing Spark Plug line is built for high-performance and competition engines that demand quick throttle response, consistent ignition, and dependable operation under extreme conditions. These racing spark plugs use a fine-wire iridium center electrode for efficient ignition in demanding applications.

Key Features:

• Iridium center electrode: Highly durable and heat resistant, it keeps its shape and performance over time.
• Fine-wire design: The small-diameter electrode needs less voltage to fire. This supports a strong, focused spark and efficient combustion.
