Knock sensor-factory rejects on Ebay question

[burijon]

Are these the infamous scabs from Nissan?http://cgi.ebay.com/ebaymotors...diweb/

What does that "B" sticker mean in the picture? Is my car really going to blow up if I use this or an aftermarket knock sensor? Will I shake worse than with my bad injector already?!?!?

I know Joe has em on sale this month for $116.50.

It'll just run in limp mode all the time when they fail.

Once you've done the labor, you won't want to repeat it any sooner than necessary.
