there is only one size for the R53 Cooper S. There was no change to the filter size during the various facelifts etc. Only changes were the difference between the stock S and
JCW/Gp or the new R56 filters. All normal R53s were the same. like Roland says those sizes are nothing like correct either...just glanced at mine in the garage and its nearer to Rolands size than the ones you have gotten from the supplier. GTT or Lohen etc in the UK can probably tell you the panel filter code ...or go on the KN website and search on your vehicle age and type and they will give you the product code.
