Laser-welded iridium centre electrode is resistant to heat, corrosion and electrical wear. The tapered ground electrode minimizes quenching. Provides outstanding acceleration, high fuel efficiency and durability.

Features:

- Designed specifically for the performance enthusiast, Iridium IX offers extreme ignitability, improved throttle response and superior anti-fouling.
- The 0.6mm 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 has superior anti-corrosion and anti-seizing properties.

For Evo Models I - VIII. Sold in sets of four.
