The increased air helps your engine run more efficiently, so you should see a small MPG increase. The downside, if your like me, is you won't be able to keep your foot outta the gas, because you like the new pull, and your mileage will actually go down.

The main thing you can do to increase mileage is drive conservatively, the boxer is VERY touchy when it comes to driving style. I can push my mileage down to 17-18 really easy.

Mechanically, these things can improve MPG:
If it just suddenly dipped:
Replace fuel/air filters - Reset ECU afterwards.

Free flow air filter or intake
Synthetic lubricants
Free flow exhaust
Smaller diameter/narrower tires(greatly impacts handling)

This is my experience on achieving better gas mileage. On the freeway, maintain a steady speed. I've driven 33 miles from home to work at about 70mph+ and got 34 mpg. (This was in an '88 Sterling 825sl that has a console computer). Drive behind big rigs, creates less drag. Accelerate slowly. Add more tire pressure to your tires. I was suprised to read that the tire pressure for the front are supposed to be 32psi, and the rear only 29psi! That seems awfully low, but hey, there Bridgestone's (whatever that means ).
Now, with the cars we drive, do we really want to do any of that crap? No. BUT, it can be done. The Impreza has a 15.9gal gas tank, lets say we run 15 gallons out of it @ 28mpg, thats 420 miles on one tank (freeway driving). I'm going to see how many miles I can squeeze out of her on my next road trip.

Good luck Buddy.
