Review on 🔌 Bosch Automotive (9617) OE Fine Wire Double Iridium Spark Plug - Single: Enhanced Performance for Your Vehicle by Glenn Rodgers

Perfect fit for my 2011 (other years will work too, just check.) Mazda 3 2.0l.at 189k Runs like new! (Not sure how old the other spark plugs were, I bought them used but they were Mazda OEM spark plugs.) Took me 15 minutes to change, anyone else has problems then you must have mixed up the required type have spark plugs. or gaping. (Of course, every vehicle is different.) Driving, idling, or accelerating was top-notch, so I assume my Mazda 3 didn't complain no matter what spacing was set, and there wasn't a single misfire or engine light. It's been more than a week, a daily driver. even through the rain. FL Driver: As is usual with some statements, people don't know what they're talking about. as if they magically believe that opinions based on personal ignorance are the only way out. The thing is, who cares where it's made as long as the damn spark plugs work the way they're designed. That's all. Almost 3 months and they still work fine.
