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. 👍👍👍.

Die NGK Iridium Zündkerze überzeugt durch ihre erstklassige Verarbeitung und die gewohnt hohe Qualität des Herstellers. Iridium-Zündkerzen wird allgemein eine effizientere und stabilere Funkenbildung im Vergleich zu herkömmlichen Zündkerzen nachgesagt, was sich positiv auf die Verbrennung auswirken kann. In der Praxis arbeitet die Zündkerze absolut zuverlässig und erfüllt ihren Zweck einwandfrei. Der Motor läuft sauber und ohne Auffälligkeiten. Ob sich darüber hinaus spürbare Veränderungen im Fahrverhalten ergeben, lässt sich subjektiv schwer beurteilen – funktional gibt es jedoch keinerlei Kritikpunkte. Fazit: Hochwertige Zündkerze mit zuverlässiger Leistung und langer Lebensdauer. Eine klare Empfehlung für alle, die auf Qualität setzen.

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.
