NGK BPR7EIX Iridium IX Spark Plug – Ultra-Fine Iridium Electrode

Next-Level Ignition Performance from the Industry Leader

The NGK BPR7EIX Iridium IX Spark Plug represents the pinnacle of spark plug technology. Engineered with an ultra-fine iridium center electrode, it reduces voltage requirements, improves ignitability, and extends the life of your ignition system — all in a plug built to NGK’s exacting standards.

The iridium electrode is 25% smaller than a platinum electrode and just 1/4 the size of a conventional nickel electrode, delivering a more focused spark for cleaner combustion and better throttle response.
