taking you back to the basics

I've had my 86 gt vert for about 7 months and haven't really been able to do anything for lack of money aside form getting new tires. Financial aid should be kicking in soon, so what does a K&N air filter do and why should i upgrade? nother thing is, any other simple upgrades or maintenance issues i should deal with. It runs pretty good and im not much of a mechanic so any help would be appreciated.
