BOSCH 9617 OE Fine Wire Double Iridium Spark Plug - Single

Tienen buena calidad y están bien empacadasLas recomiendo.

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.

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

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

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.
