On a Civic of the age of ours, because of the intake manifold sensor type it uses (MAP not MAF), I agree a WAI will help FE modestly. Here were
my test results with my WAI on my 1998 Civic. I totally see the value of just using PVC plumbing pipe. That is how I built mine for just a few bucks. Maybe Daox will correct me, but I thought nobody here had yet ABA tested a CAI to see what it might do. Still, I would agree with him that the CAI will probably not help for the simple reason that a CAI is supposed to add more dense air to the air/fuel mix and therefore get the ECU to increase fuel in the mix, no? If so, you would use more fuel and increase pumping losses, no? Anyway, a WAI is easy to build. Mine is black PVC pipe from the stock filter housing to a spot over the exhaust manifold (HOT air).
Good luck!
