Fit type: Vehicle Specific. Iridium alloy has extremely high melting point, giving it high durability to heat and electrical wear, perfect for today's high performance engines. The 06 millimeter laser welded fine Iridium tip ensures high durability and a consistently stable spark and the tapered ground electrode minimizes electrical quenching effect.


Trivalent metal plating provides superior anti-corrosion and anti-seizing properties; Part number of spark plug inside the box: BKR5EIX-11.

Enhance performance: the iridium alloy used in the NGK Iridium IX is six times harder and eight times stronger than conventional platinum and can handle temperatures associated with fuel-injected and turbocharged engines.

Designed specifically for the performance enthusiast, Iridium IX offers extreme ignitability, improved throttle response and superior anti fouling. The 06mm laser welded fine iridium tip ensures high durability and a consistently stable spark and the tapered ground electrode minimizes electrical Quenching Effect.
