i have a 2004 mitsubishi eclipse gt, i was wondering if i can get tips on what to do for my care. Hp wise and looks

i got an aem intake
and tein springs

 

you could get a header and a catback exhaust. There is a large aftermarket for that car so you shouldnt have a problem finding parts. Looks just do whatever you like, its all opinion. But rims is always a good place to start

and just in the future if you have multiple questions can you please put them all in one post and just # the questions so that you dont have a bunch of separate threads. Thank you
