### ⭐⭐⭐⭐⭐ Review
*by N***W on 30 July 2025*

Replaced the NGK LMAR8A-9S (6817) with this and the difference in smoothness and power delivery is tangible. Has the correct Honda spec washer of the LMAR8A-9S (6817), WHICH IS NOT THE LMAR8A-9 (4313) listed both in the 2014 Forza owner's manual and what Amazon confirmed fit says is the correct plug. Spent hours researching why the 4313 plug wouldn't start my bike before I stumbled across this subtle but significant difference. Yeah, for a spark plug it's kinda pricey, but one plug in my bike is not a wallet breaker, and the longer replacement interval and better performance make it a bargain.
