I'm no purist, I'm just going for simple mods/upgrades. So don't give me the "if you want power, swap this....turbo that....bore this...blah...blah..blah.blah" The car: 93 si coupe... I bought it with an aftermarket exhaust, I don't know the make. I'm just wondering what an intake will give me, performance / sound / fuel efficiency or any other factors they will contribute to my car. And whats the difference between, say an AEM and a cheap one, bomz (as seen on ebay for $35) I've heard that an aftermarket intake will rob you of power from a friend...but he's a hater (he drives a "pimped-out" 4-door sunflower...i mean sunfire) any way...enough about "Mom" cars... Give me the +/- of intakes and some suggestions as to which one to get.
