Hi I just bought the kics drain plug for my engine and it comes with 2 washers which one do I put on for my 03 350z ? and do I still use the normal copper washers on top of it that I bought from the dealership ? Im so confused lol

 

Neither of those looks like an OEM crush washer so I would just stick with the one already on your car.

 

Ok so just use the normal oem crush washer and put it on this one correct ?

 

Doesn't really matter, as long as the size is good for a proper seal.

 

ok well on the packaging it says for Nissan and Toyota

 

I installed it with the copper washer on it from the dealership so far no leaks hope it stays this way..
