High quality long lasting plug!
Why did you choose this product over others?: I wanted a 'long lasting high performance plug for my Thruxton R and this appeared to fit the bill! I changed several things at once (stale fuel, redex, plugs, air filter so it's not possible to say I 'noticed a marked improvement' just because of this!

Super Plugs.👍👍
I got fed up keep changing plugs on a Yamaha MT07 Tracer. Every time you have to change the plugs you have to half strip the bike. 😖😖😖. So now I have these plugs fitted which should last at least THREE +times longer. 👍👍👍.

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.
