What performance work should i put into my nissan altima 2010 sl with $500 its all stock now.
I want to slowly upgrade my cars performance. looking for any idea for parts
and also im not handy so installation is a factor
A cold air intake is the easiest way to have horsepower gains on the cheap and do it yourself.
A low restriction muffler might get you a couple of HP but $500 does not go very far when looking for performance.
