so i just filled up my 3.8 engine impala for 50 bucks x( and i was just wondering is there any mods we can do to increase the mpg a little bit and would give us a little bit more power like a intake increases power and gives a few mpg extra is there any more mods like that ?
let me correct your first statement... You can really save on gas if you plan trips accordingly so that you do everything in one trip out rather than make a whole bunch of small trips for everything. This effectivly will cause you to drive less since you are driving smarter, and you will save money. also you can get your car tuned, it is possible to tune the pcm to run more fuel efficient by making fuel the limiting reaction instead of of O2 which is what is currently the set up. this can be done my setting the goal stoic. to 14.7 - 15 durring normal temp operation parameters. however it needs to be done proberly cause the coolent system needs adjustment too, to counter the lost effects of the evaporative cooling of the gas so that your engine doesn't over heat, and the cylinders still stay cool enough.
Fill up from empty is around $85.
Can't complain though... it's much more comfortable than the Impala, and isn't too bad yet. Once it gets over $4, I will park it. I parked the Impala last time gas got above $4 here...

If you replace them get AC Delco Iridium plugs and AC Delco wires. If you know they have been replaced somewhat recently, I wouldn't be in a hurry, but if you don't know the history of the vehicle I'd do plugs, wires, fuel filter, etc.
Protip: If you don't know what you're doing, don't do it.
