I recently put a set of new BOSCH Plat plugs in my car...

...Well they turn out to be shot..The little bend is all white and the plugs look like the old ones....But I cant find a reason for this to happen...

You answered your own question.

Unless you can validate that there are other reasons for your plugs to be toast, the reason you are experiencing this is because they are Bosch plugs.

They are one of the worst plugs to use in a SR20DE. The engines do not like Bosch.

Stick with proven quality and reliability, stick with OEM NGK PFR6B-11(PFR6G-11 new part#) Platinums or BKR6E Coppers.
