Superb price for a top notch spark plug. The engine is noticeably smoother. I’ve used this on inline 4s and big singles. Both were noticeably better with these plugs and I’d recommend them to anyone wanting a little something extra to make their vehicle run that tiny little bit better. Better idleing and smoother Rev Increase.

Don't kid yourself. You are not good enough to notice any difference and / or see any better fuel consumption.

I have an 05 yamaha majesty. Didn't notice much difference however that's just me. This might show better performance depending on what your using it on. It was only 2$ more then the regular one and these are supposed to last long. We shall see only the future will tell.

I took the old one out and fitted this one in its place. I switched the ignition on and the bike started a treat and it now goes really well. Thats all I want from a spark plug!! (Sorry if this review sounds daft, but you did ask)
