If you don't mind spending the money it wouldn't hurt. They are notoriously prone to partial failure.
The mount looks a bit like a tripod with the end of the engine sitting on top of it, connected with a 17mm bolt in the centre.

There are both. AWR make a side engine mount but the feed back suggests it's pretty harsh. I don't know how much a stock mount is but replacing it seems to make a big difference according to ppl who have done it.

Diver side engine is now changed to brand new stocker. All noises had gone and the car is now silky smooth as brand new on day 1. In side the cabin, you just can not notice the engine is running if you dun rev it. =D
Oh, I have also changed the lower control arm bushes, they are all worn out.
Bloody awesome.
