BOSCH9617 OE Fine Wire Double Iridium Spark Plug - Single

Perfect fit for my 2011, (other years will fit as well, just check.) mazda 3 2.0l.at 189 k it runs like new! (I am not sure how old the other spark plugs were, I bought it used, but they were mazda oem plugs.)took me 15 mins to swap, anybody else has issues then you must of messed up with the type of spark plugs needed or the gaping. (of course each vehicle is different.)driving, idle or accelerating has been top notch, so i assume whatever the gap is set at, my Mazda 3 has not complained and not one single misfires or check engine light. It's been over a week, daily driver. even thru rain. FL driver.as usual, with some statements, people don't know what t f they are talking about. as if they magically believe the opinions based on personal ignorance is the only way to go. point is, who gives a crap where it was manufactured as long as the darn spark plugs perform the way they were designed.that is all.almost 3 months in and they are still performing well. (fl chilly weather or when it's hot, humid and 90's) 6/3/2021April 2023 and zero issues w these plugs.

Very nice plugs that made an immediate difference in starting and mileage. Would not hesitate to buy again.

Great plugs. Changed at 120k miles. Gas mileage increased from 19 to 25mpg with a noticeable increase in engine power. Look identical to the OEM branded Bosch plugs. Though Bosch does not recommend this part number plug for the 4cyl Escape. They work great. I'm happy.

Possible package damage but one of the six I purchased had corrosion and rust on the threads, I was able to clean the surface rust off and it’s working as it should

Work great and it’s been several years and still working out great. Saved a ton of money.

Funciona bien, se recomienda alta durabilidad y calidad.

Work on my car, Ford Fusion 2.4L ... so far so good and I don't feel the car any less performing than the stock iridum, which is NGK iriduim plug! This bosch is the best price at the time of purchase ($6 a pop) with same good performance with stock plug! Only time will tell if this will last as long as NGK, with in my case, 70K

I bought these plugs based on Amazon's description stating the country of origin as Germany. Three of the four plugs were in fact manufactured in Russia. I don't need anything from Russia. Also the plugs came poorly packaged, loose in a large envelop. All of the boxes were crushed and two of the spark plugs were out of their boxes with no protection what so ever.

Made in China. Made the replacement. Received the same Made in China.

Tienen buena calidad y están bien empacadasLas recomiendo.

Me llegaron solamente 3 bujías Bosh Made un china, luego Amazon me envió otra bujía marca Bosch Made un Germany. Ojalá las 4 hubieran sido alemanas.
