Performance parameters
Core Performance Parameters
Melting Point:
The single iridium center electrode has an ultra-high melting point of 2,454°C, surpassing platinum (1,772°C) and standard nickel alloys (1,455°C). This enables it to withstand extreme combustion chamber temperatures without degradation.
Service Life:
Under normal operating conditions, the spark plug delivers a lifespan of 60,000–100,000 km-4–5 times longer than conventional nickel alloy spark plugs (15,000–20,000 km).
Ignition Gap:
Precision-engineered to 0.8–1.1 mm, ensuring optimal ignition stability across engines of varying displacements and power outputs.
Insulation:
The high-alumina ceramic insulator features a dielectric strength of ≥30 kV, effectively preventing high-voltage leakage even under severe thermal cycling.

Core Advantages
Product Advantages
Powerful Performance, Instant Throttle Response
The ultra-fine iridium center electrode (as thin as 0.4mm) reduces the required ignition voltage, generating a more concentrated and powerful spark. This ensures instant ignition of the air-fuel mixture for complete combustion, dramatically improving cold-start efficiency and delivering unmatched throttle response with sharp acceleration.
Exceptional Durability, Cost-Effective Maintenance
Iridium's superior hardness and thermal stability extend this Single Iridium Spark Plug's service life 4–5 times longer than standard nickel alloy plugs. Eliminate frequent replacements: install once for long-term reliability, significantly cutting downtime and maintenance expenses.
Stable, Reliable, and Universally Compatible
Whether navigating city traffic with frequent stops or cruising on highways, this Single Iridium Spark Plug delivers consistent ignition performance. Its robust material construction ensures dependable operation under extreme conditions, providing peace of mind on every journey.
