We supply both genuine (OE) and where available, Aftermarket parts. An Aftermarket part will have a P (pattern) suffix at the end of the MG Rover part no. Other suffixes such as UR (uprated) and SS (stainless steel) are also used to denote other variations of the same part. These are shown as options below the originating part no. See MG Rover MGF & MG TF Vehicle Information for detailed information. See alsoParts Information for further details.
