DENSO 5616 Iridium Long Life Spark Plug

The DENSO 5616 Iridium Long Life Spark Plug delivers superior ignition performance and extended service life for a wide range of automotive applications. Featuring a 0.4mm iridium center electrode, this spark plug provides improved ignitability, better throttle response, and enhanced fuel efficiency compared to traditional copper or platinum plugs.

Key Features:

• Ultra-fine 0.4mm iridium center electrode for superior ignition performance
• Extended service life up to 60,000-100,000 miles depending on application
• 360-degree laser welding for maximum durability
• Improved fuel efficiency and reduced emissions
• Better throttle response and engine acceleration
• Manufactured to strict OE performance, durability, and emissions standards
• Resistor type for reduced electromagnetic interference

DENSO Iridium spark plugs are engineered to withstand extreme temperatures and pressures while maintaining consistent performance. The iridium construction resists wear and erosion far better than conventional materials, ensuring reliable ignition throughout the plug's extended service interval.
