So I decided to change my oil today and couldnt find the plastic cup thinngy to loosen the oil filter cap. Went ahead and tried to loosen it by hand and some how cracked it a little bit. Thinking everything was fine filled up oil and started car. Went to check everything and oil was spilling from crack on filter cap.

So can anyone help me on where to get it and if only the dealer has it does anyone have part number? Also now much does this run?
I dont want to drive my car like this and have more damage so I need one very soon. Thanx for the help.
