I bet the bean counters had as much to say about the NSK as the engineers.
I would also bet NSK is quite competitive with OEMs as any other. just gouge replacement parts.
I bet the bean counters had as much to say about the NSK as the engineers.i would use what they reccomend for original replacement,the scientists at nissan have already decided that what they put in there will work best,everything else is just a gimmock to make money on some suckers,gold platnum irraidium copper all respond diffrently to varied heat range and time exposed to that heat range,some last longer than others some do not,make your own choice,just make thge right one
sorry, ngkwhats NSK?
