Double Iridium Spark Plugs

Description

– Double iridium spark plugs are high-performance ignition components with iridium laser-welded onto both the center and ground electrodes.
– This design provides superior durability and performance compared to standard copper or even single-iridium spark plugs.
– They offer benefits like longer lifespan, improved fuel efficiency, and enhanced engine responsiveness.

Key Features:
Iridium Electrodes:
Both the center and ground electrodes are made of or coated with iridium, a durable precious metal.
Laser-Welded:
The iridium is typically laser-welded to the electrodes, ensuring a strong and reliable connection.
Fine Wire Design:
Many double iridium plugs feature a fine wire center electrode, which improves firing efficiency.
Pre-gapped:
Some brands like Bosch offer pre-gapped plugs, simplifying installation and eliminating the need for adjustments.
