Bosch products are the next best replacement auto engine parts near OEM.
A great made spark plug. Well worth the the price spending for replacement auto parts.

they work fantastic for my 2011 mazda 3 2.0l. no gapping needed if stock.
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) 6/3/2021 April 2023 and zero issues w these plugs. April 2026. Perfect. :)

Item arrived opened and with damage
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

Good plug. Let's see how durable it is!
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

Fit 2010 Ford Escape 4cyl
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.
