The NGK BPR7HIX Iridium IX spark plug is the iridium fitment for classic two-stroke machines — the RX-series Yamahas and TVS two-strokes that still command a loyal following. It's the NGK-recommended iridium plug for these engines, a direct OEM-spec replacement.
The 0.6mm fine-wire iridium centre electrode fires a sharper, more focused spark than copper — which two-strokes especially appreciate for cleaner combustion, reliable starts, and consistent firing. Iridium resists fouling and holds its gap far longer, a real advantage on engines that run rich.
Direct-fit, OEM-spec replacement. No tuning changes — just a sharper, longer-lasting spark.
