The NGK Iridium IX BKR5EIX-11 is a single iridium-tipped spark plug with a fine center electrode and a preset gap of about 1.1 mm. The 0.6 mm iridium tip is far smaller than a platinum or nickel electrode, which lowers the voltage the ignition system needs to fire and helps the plug keep a sharp spark as it wears. It suits drivers who want a long-life plug for a stock or lightly tuned engine. Against platinum plugs it trades a higher price for finer firing and longer service life; copper-core nickel plugs remain the cheaper baseline.

The NGK Iridium IX is a spark plug, model BKR5EIX-11. It has an iridium center electrode that is 25% smaller than a platinum electrode and one-quarter the size of a conventional nickel electrode.
