NGK Iridium IX. A 0.6mm fine-wire iridium centre electrode in place of a conventional one, firing a sharper, more focused spark.
On a higher-revving sports engine that means crisper throttle response, easier cold starts and more consistent ignition, held steady by an electrode that barely erodes.
Direct fit. Nothing to adjust.

R15 V3, V4 and the MT-15 take the MR8E-9, a standard plug. NGK does not make an iridium version for those bikes. If you want an upgrade for a V4 or MT-15, the Ngage B8RII-8 is the one to look at.

Arrives pre-gapped and ready to fit. Thread in by hand first, then torque to your manual's figure. If you check the gap, move the outer electrode only.
