Spark plugs for your Yamaha IT250
The recommended plug is a BR8EIX. Match that code - spark plugs are thread-, reach-, and heat-range-specific, so the part number matters more than the brand. Worth considering: the BR8EIX iridium upgrade - it fits the same port, fires cleaner, and lasts far longer between changes.
