No one makes a "cold air intake" for a e30. And if they did it wouldnt be much good unless you route it under the wheel ledge. Theyd be expensive and not do much anyway. Just go buy the boot. BMW dealership sells them for $28, i just replaced mine. You can find them online for around $18 but then you have to pay 7 or so in shipping and still wait a week. Its better just to pay the $28 bmw asks for and have it that day.
