If you feel some sluggishness going uphill or when passing the plugs MAY be fouled and needs replacing. If you did not have any idea when the plugs were installed then I'd do them right away.
You can go to the dealer or you can also do it yourself. Changing oil and spark plugs on a BMW is sometimes easier to do than any domestic cars. Later BMWs have coil over plugs which means an individual coil on top of every spark plug. Plugs are most likely Platinum-tipped and could be Bosch Platinum+4 or NGK. Plugs can be purchased from Canadian Tire, PartSource or an auto supply chain and not a dealer only product although you can call the dealer to make sure of the part number.
