About this item
- Designed specifically for the performance enthusiast, Iridium IX offers extreme ignitability, improved throttle response and superior anti-fouling
- The 0.6 millimeter laser welded fine Iridium tip ensures high durability and a consistently stable spark and the tapered ground electrode minimizes electrical quenching effect
- Longer insulator nose prevents fouling, the corrugated ribs on insulator prevents flashover, and a triple gasket seal eliminates combustion gas leakage
- Iridium alloy has extremely high melting point, giving it high durability to heat and electrical wear, perfect for today's high performance engines
- Trivalent Metal Plating provides superior anti-corrosion and anti-seizing properties
Key Features
- Iridium-alloy center electrode for a finer spark and lower required voltage
- Laser-welded tip resists electrode wear over extended service intervals
- Trivalent metal plating on the shell resists corrosion and seizing
Technical Specifications
- Electrode material: Iridium alloy
- Application: Naturally aspirated and turbocharged gasoline engines
- Service interval: Extended vs. copper-core plugs (check vehicle manual)
