This was originally for a 430 but I took a chance and put it on my 2001 clk320. It gave it more rumble, used for less then 5,000 miles. This is very very rare. When I bought it the item was near $2,000.00 .. Now you cant even find them.
Please make sure this will fit on your car before buying. I. Im sure you will enjoy it, I have no bad thoughts about this item.
