I've tried all sorts of spark plugs over the years, trying to save a buck here and there... Each time I've done so, I've had to go buy an NGK to get things running properly again. Overheating plugs due to inaccurate heat range rating, galled threads due to cheap metal in the base, insulator crumbling to dust, electrodes eroding extremely fast, and crazy misfires are all issues I've found with other, cheaper brands of plug. Not once have I had an issue with an NGK plug that wasn't caused by my own ham-handedness (socket slips, dropping them onto concrete, etc...). NGK for trouble-free operation.

I bought these for my 2012 Ninja 250r because upon doing routine checkup at the start of this season, I noticed the spark plugs looked bad. In fact, I think they were the original factory ones by the way they looked. These arrived in three days and were the exact same thing as what was in there and work even better. Make sure you gap them first though! Highly recommended!
No frills, a simple spark plug that works as intended.
Tried other plugs and have always gone back to NGK's? You can't go wrong with these plugs!
Because without this, I would have no power. Always had good luck with NGK spark plugs.
They are dependable.
It works. Can't say I noticed an increase in power, and the 'style' rating is kinda weird for a review of a spark plug, but as far as spark plugs go, this baby is James Dean.
Great plug! I will only run this spark plug in my motor.
