99 Civic Upgrades?

Whats up guys, yes i own a MR2, but also i have a 99 Civic EX auto, its my cruiser to work but i wanna know if there r any upgrades i can do to the engine to get more out of it. All i have in mind so far is an AEM CAI and DC Headers, supposedly they r the best. anything else i can do??? thanks

throw on an exhaust, maybe even a cam, underdrive pulley's, cam gear. if you wanna get really brutal then up the comp ratio, buy an intake mani with a bored tb, hi flow fuel rail, fuel press regulator.

i would suggest a motor swap but it looks like you dont wanna do that.
