So i'm in the lookout for a knock sensor, so i go on ebay looking for a KS and i see two different ones.

A Genuine KS (or so i believe) that i was outbidded on:

LInk1

And then there are these (many available):

Link2

Now my question is this, are they both really the same? And am i safe with purchasing the 2nd one even though its a little more money.

Thanks for your help

second one should be fine
