my mother has a 04 9-3 arch i believe and i'm just looking for some ways to give her a few more ponies....

i can justify spending the money, just need results. i was first looking at a small intake kit, i know on some cars it makes no difference and if it doesnt in this cars case i wouldnt buy it etc etc.

so steer me off in the right direction here ladies and gentleman

 

"Arc". An intake will get you nothing but noise. A cat-back exhaust might get you ten hp. A PPC ECU upgrade will get you 39 hp and 64 lb/ft of torque. My BSR PPC Stage One has my 05 Arc putting out 249 hp and 286 lb/ft of torque. They're the only real upgrades available, but they're pricey ($800). Hirsch, Engstrom, and Nordic also sell ECU upgrades.
