Question

i have a 2000 honda civic si with a b16 engine with no intake...how much hp will i gain if i add an AEM Cold Air Intake?

Answer 1

for a B16 motor nothing beat changing the ECU to a aftermarket ECUs from MUGEN or Spoon.. for a cold intake and a correctly tune exhaust u will probaly gets around 10-15 hp increasement.. add the mugen/spoon ECU, you will get an additional 25-30hp.. if you on a low budget.. get an Apexi V-AFC (it a piggyback ecu's for fuel&Vtec controller)..

Answer 2

i have a greddy evo 2 on my 2002 civic ep3. it gives a LOT of hp, around 10-12 in the high end, high revs, and sounds beautiful, bass heavy and sweet... not ricey at all. with the intake look for about another 7-10 hp, in the high end. with both, youre going to lose some low rpm torque/grunt, but once you get going, look out! have fun!
