9607 OE Fine Wire Double Iridium Spark Plug - Single | Replaces 3764 6741 53364. OE-grade replacement.

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.

2003 Kia Spectra - The 4 spark plugs were shot. So terrible. These Bosch plugs fit wonderful and the car fired right up. Shop wanted to charge me $10 a piece for Platinum plugs but I found these on Amazon much cheaper and supposedly much better. Great product! Thank you!

this product i bought for my boyfriends BMW and it needed them bad cause its got almost 200,000 miles on it. so i got him an early anniversary present! ~there is nothing i don't like about these they are perfectly fine. when we got them he didn't know how to change them out but these spark plugs for that specific model is easy to put in which is nice. i would recomend it to who ever had the same model or if they would fit in another bmw.

They're doing their job. Great brand and haven't had any issues if I remember correctly these were cheaper than purchasing at my local Auto parts store. I'm a sucker for saving money but maintaining my quality. Buying again when it's time for another tune up

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.

Excellent product, very good quality.

These were purchased for a standard plug replacement. I had a knock/ping on heavy acceleration and it's gone thanks to these new spark plugs. They run smooth and the acceleration is smooth and sure. I'll stick with these for all my future replacements.

I did't have a chance to install them yet but i'm using the same (platinum type) for 7 years now.

Excelente precio, ya llevo tiempo usando las de Iridium en mi coche y solo las limpio una vez al año, está será la primer vez que usaré las doble Iridium

Exelentes bujías supera a las originales

El pedido fue de 4 bujías bosch de doble iridium y solo llegaron 3 y otra mas de doble platino y las cajas golpeadas y abiertas
