2008 Mondeo XR5 Turbo - need advice/info on upgrades

[5yan5]

Hi everyone this is my first post and I'm hoping I can get some information and tips on what the best upgrades to start with to give my Mondeo XR5 Turbo a bit more power. I dont want to build a race car or anything ridiculous but I want to give it a good boost in power as it is stock. I am pretty much a newb when it comes to cars but I have a little bit of knowledge and want to learn if anyone is willing to help. Also wondering where I can purchase whatever parts I need to get online if possible. Any tips will be greatly appreciated. Thanks
