Review: I have to say I was a little worried, the picture didn't show the other end and I was a lil scared that I was going to get the wrong part. Other than that I'm impressed on how fast I got them and the price! The cheapest I found them so far. I have a 2005 Honda cbr 600 rr and they where the right ones for my bike, runs like a champ! Thanks

El fabricante recomienda dos marcas de bujías Denso y esta que es NGK para las cbr1000rr, y las recomienda por que ambas marcas son sinónimo de CALIDAD. En este caso este es el modelo en ngk para las cbr1000rr de 7ma y 8va generación
