Boxster Ignition Switch Cross Reference

I thought the 4B0 switch was for 2004 and up and the earlier cars took the 4A0 switch. My '00 S has the 4A0 p/n.

If the part had been updated to the newer style it’s the B designation. You are correct in that the original piece is replaced with the A designated part number.
