    good intake to go w/ H23 TB/Plenum

    Hey guys I'm wondering what intake size is the best for the H23 tb/plenum swap i just did. My 2.5 in. AEM CAI is kinda small for it so i'm looking for a new one. I prefer a CAI vs short ram. So would i have any fitment issue with a 92-96 prelude one? or would the 97-01 be better? b/c right now, the coupler going onto the TB for my current intake is stretched so i'm thinking more power could be had by a bigger diameter piping/filter. I just dont wanna deal with modifying too much stuff.

    If you search on ebay, there are a few companies selling intakes for the accord that they claim is 3" piping....probably your best bet.

      so something like this on e-bay? here's the deal though, one costs 31 bucks and the other costs 45 w/ shipping included for both, which should i get? they're both the same it looks like... And get what, like a 3" K&N filter to put on it separately?

        Just get the cheapest one if you like how it looks....and I suggest an Apexi Power series filter over K&N. I had a K&N for a bit and my oil analysis were showing an increased amount of silicone (dirt from intake air). The Apexi flows great but filter better plus it's a dry filter so no re-oiling to deal with

          A 3" intake is overkill. Your AEM will be fine. Since you're running a full CAI it might not help to get a BPI flowstack, but if you're running a short ram, it would definitely help. Then get an AEM Dry Filter to finish it off, and that would be a nice setup.

            The 2.5" AEM cold air is smaller than the TB. It therefore will have issues flowing as well as the TB, which in turn makes it a restriction.

              the 92-96 prelude and 97-01 lude intakes are basically the same.

                i have the ability to make a short ram of my AEM CAI since i've got the bypass valve on. Should i just get rid of the bypass and relocate the filter on top for quicker airflow? or will it not make a difference?

                  A 2.5" pipe can only flow so much...
