Grab yourself a cold air intake first thing, then upgrade your exhaust if you have the cash. Even going with a cheap 30$ dynomax muffler and some 2.5" piping. A muffler shop will charge you around 100-150$ to custom bend the piping and weld the muffler on. Don't worry about upgrading the ignition system and stuff until you get some other bolt ons that require more fuel or spark first.

There is also the free tweak of advancing or retarding your timing for better top or bottom end performance. Make sure you have a timing light handy in case you need to set things back to the way they were.
