How do i know this because first when I put Bosch 4Platinum in my Maxima , it drove like crap and the plugs were done after 15000km, and when i put back the NGK in it , it drove like a charm.

As I am not the scientist...just an average old dude who can tell when his car is getting good mileage and doesn't need hundreds of dollars in scientific equipment to know it...I can tell these plugs are OK. They give me more power but I haven't had them long enought to really tell if they give me better mileage. Some people need scientific testing to determine this, but I guess I am old school and judge from how much I am spending on gas to determine if I am getting better gas mileage.

I saw quite a few customer comments from people that had bought and installed them. They claimed they has a slight increase in mileage.

So I thought what the heck, why not.
