The problem with the AEM is that it would get real hot from engine heat and the water bypass valve caused a lot of extra noise and dirty air to be let in. Even worse, with the AEM intake behind the bumper and all that air flowing around that bumper I think it put the intake into a very low pressure zone. My ET would drop 0.3 seconds whenever I removed my right front turn signal. Obviously without the turn signal air could flow directly to the intake and gave a couple HP at speed. I couldn't drive around with no turn signal and there was no aesthetic way of making a opening in the bumper for the intake. I really wanted a fresh air intake with a slight ram air effect.

So I got an OEM air intake tube for a 5th gen Prelude which is actually larger in diameter than the 3" 5th gen Lude AEM CAI I was using. I cut it to fit to the stock Accord airbox and put in a K&N filter. Since my battery is in the trunk, there's a straight path from the airbox to the front of the car so I got a 3" plastic subwoofer port with a nice curved flange end. God only knows about the frequency and tuning of the port, but the sub flange seems to act as a nice velocity stack. With it and the stock intake tubes the engine is sucking as much or more air than it did with the AEM CAI, plus it's getting plenty of direct fresh air flowing around the headlight. The power delivery and sound are much nicer than cold and hot air intakes I've used.

 

possibly cut a hole in the grill, and run a direct port to the area the intake "horn" is?
