I just got a 2012 Genesis 5.0 as my first car and I would like to do some work to it but nothing crazy for I will probably be getting rid of it within the next year. First things that came to my mind were cold air intake and an air filter.. Are there any other modifications that are relatively cheap and give me some horsepower gain? I'm also unsure as to what air intake and what air filters are the best. Any help is much appreciated, thanks in advance.
