NGK Iridium Spark Plug - BPR7HIX
NGK Iridium Spark Plug - BPR7HIX
This is the only plug in our iridium range specced for two-stroke engines rather than four-stroke. Two-strokes burn oil in the fuel mixture, which fouls plugs faster than a four-stroke, so while the core iridium benefit, a finer, more consistent spark, still applies, riders may find they need to clean or replace this plug somewhat more often than an equivalent plug on a four-stroke engine.
It's a direct fit for the Yamaha RX100, RX135 and RX-Z, and the TVS Shogun, Samurai and Shaolin, all classics that are long out of production but still very much on the road.
Suitable For
- TVS: Shaolin, Shogun, Samurai, Scooty (2-stroke)
- Yamaha: RX-Z, RX100, RX135

FAQs
Q1: Does an iridium plug work differently on a two-stroke engine?
A1: The core benefit, a finer and more consistent spark, still applies, but two-stroke engines foul plugs faster since they burn oil in the combustion chamber, so it may still need cleaning or replacement somewhat more often than on an equivalent four-stroke.
Q2: Is this plug still genuinely available for an RX100 today?
A2: Yes, the BPR7HIX remains part of NGK's current catalog and is listed as a direct fit for the RX100, RX135 and RX-Z despite these bikes having been out of production for decades.
