These plugs are engineered by DENSO, a leading global manufacturer of automotive components, and are recommended for drivers who demand superior engine performance and reliability.

Each plug in this set features an iridium center electrode, which offers several advantages over traditional copper electrodes.

These plugs are suitable for a wide range of applications, including both domestic and import vehicles. The 15-6 designation refers to the thread pitch and reach, making them a universal fit for engines with a 15mm thread diameter and a 6mm thread reach.

The DENSO 3439 Pack Iridium FxE20HR11 15-6 spark plugs come in a convenient packaging of six plugs, ensuring that you have a complete set for your vehicle. Each plug is individually boxed for protection during transportation and storage.

Installation of these plugs is straightforward, and they can be replaced using standard tools and procedures. Following the manufacturer's instructions for installation is essential to ensure the longevity and optimal performance of these plugs.

In summary, the DENSO 3439 Pack Iridium FxE20HR11 15-6 spark plugs are an excellent choice for drivers seeking high-performance and long-lasting ignition components. Their iridium center electrode, narrow electrode gap, and universal fit make them a versatile and reliable option for various types of gasoline engines.
