Hey,Im recently looking into getting the sf intake with the box so it doesn't attract the heat from the engine. I was wondering if im going to need a tune if i swap it in. I have a 05 lgt automatic. on the cobb website for the intake it says that subaru of 08+ needs a tune so I don't know if i truly need a tune. and if i do do i need to get it right away or is it something that i don't need to worry about. and if i don't get a tune what problems would it cause. please lmk asap thank you!
