DENSO Iridium TT Spark Plug

The DENSO Iridium TT spark plug is a fine-wire iridium-tipped spark plug designed for reliable ignition, smooth idle, and strong throttle response. Iridium TT plugs are engineered as OE-quality replacement spark plugs for a wide range of gasoline engines.

Key Features:

• Twin-tip design: Fine-wire iridium on the center electrode and a platinum tip on the ground electrode help resist electrode wear and keep the gap stable over time.
• Reduced firing voltage: The small-diameter center electrode concentrates the spark, which supports easier starting and more efficient combustion.
• Long service life: Durable iridium and platinum alloys are made for extended service intervals compared to conventional nickel plugs.
• Consistent performance: Helps maintain steady idle quality, throttle response, and fuel efficiency.
• Quality construction: DENSO is a leading OE supplier of ignition components and builds its plugs to strict quality standards.

Whether you are replacing worn plugs during routine maintenance or restoring engine performance, DENSO Iridium TT spark plugs offer dependable ignition and long-lasting durability. Choose the correct part number for your application from the available options.
