Im doing a full tune up my 2003 325xi beamer & i wanted to get some info on if it would be a good idea to replace my coil packs and boots when changing my spark plugs or just replace my plugs?

If you don't have any misfires then I would skip the coils unless you just want to spend the money, Save the old ones if they work well as you might want them later.

You could add a set of high performance coils which are not that expensive.

Thank you. So I should just replace the sparks? Because I don't have any misfires.
Hello, could I just replace the spark plug if I have some misfire? Will that help or it's mandatory if I want it to run well?
