I am a fairly new owner of a 94 Maxima GXE, in very very nice shape. The car already has a couple of mods, and I've put $700+ electronics into it, now I am looking for some other easy upgrades. I've got a K&N Air Filter coming, anyone have an opinion on these? This is my third car, first foreign...if only I had known.

 

It sounds like your on the right track to modding. Here's some DIY options: exhaust(suck it in/ blow it out!),8mm plug wires,Ignition System (Jacob's has one that plugs right in a matter of minutes; ICE pack), fuel pressure riser, a CAI, under drive pulley, tranny cooler for auto/ redline or royalpurple synthetic gear oil for manual tranny, ecu (which is LAST, it works to enhance the mods you have already)That's just a run down of possibilities in the engine bay. Then you have suspension and body. Hope this helps!
