Is the K&N panel filter for B5-S4 the same for B5-RS4?

[R12]

I'm looking for the proper details to buy one, i.e K&N part number. I have searched but just found general references. I can buy it in the US or here in Europe. If in the US, I know how to order (if it's the same as that for the S4).

Thanks in advance.

I found the part number for the K&N panel filter, just in case anyone runs into the same doubt...: 33-2125
