Yes, you should replace the spark plugs in your Forester at the intervals recommended in your owner's manual.

New spark plugs and possibly plug wires.
use a bendy extension with your plug socket on the end. Available in a good socket set such as Teng-Tools. Dan,
Follow recommendations in your owner's manual.
1-3-2-4 Since there is no distributor, I cannot imagine why you would need to know this. Is there a practical use? --Ken
If you look at the distributor of the car, sometimes they are marked with the cylinder number on the cap. Find number 1 and follow the spark plug cable to the spark plug. That will be No. 1 cylinder.
Just check this thread - it has pictures and a good description. http://www.scoobymods.com/forums/showthread.php?t=3017
There is one per cylinder. Most of the 2003's have a flat, opposing 4 cylinder engine. The plugs can be very hard to get to with the engine installed but with patience and a little ingenuity it can be done. You'll need to make good use of short extensions and wobbles (universals) but it can be done. If you have the six it is easier. You'll know if you have the six cylinder because it is emblazzoned on the back of the car.
