Automotive (9607) OE Fine Wire Double Iridium Spark Plug - Single

Excellent, I put them in my car and you really feel the difference... I recommend them...

Funcionan genial. aumento un poco de potencia comparado a las bujias de platinium que tenia instalado el vehiculo, espere que funcionara mucho mejor en vista que se instalo de estas mismas bujias en otros vehiculos, mejora el arranque y combustion, espere que mejorara el consumo de combustible y todavia no he visto mejora significativa.

the items do not fit. are of different sizes yet it is said on the amazon that it will fit a mazda 2. The items i ordered arrived well and are exactly what i had ordered. The issue is that it said on amazon that it would fit a mazda 2.....they dont. I cannot afford return the purchased items as it would cost me than i had budgeted for...

looked nice easy to install and showed more performance at higher RPM's

Bought these plugs for an 07 Kia Optima that I bought from a private seller. The car has 180K and needs some attention under the hood. I was surprised when I pulled the plugs and realized that they had been in there since the car was built. Factory Denso plugs. Unbelievable to me. The first picture is one of the old ones beside the new Bosch plug.
