In engine bay area,reducing ur engine vibration thus reducing power loss during gear shifting. Wher to find pics ah? U can try marketplace wher got ppl selling it.

Oh yea i did a search in google and they said it reduces vibration.but does the torque dampener comes standard with this engine?if it does not i would like to know why it still behaves that way as when i newly trasplanted the engine it does not vibrate at all.could it be warned out?
