I doubt you will lose power due to i/h/e, but it is possible. Highly unlikely though. Depends though on what you put in. If you drop 3" exhaust you might lose alittle bottem end, but gain top end. If you use 2" piping...you might lose top end but gain bottem end due to back pressure.

you are wrong

the concept of combustion is this... you MUST have enough air for the fuel, and enough fuel for the air... IF stock civics ran REDICULOUSLY rich, and you added all these AIRFLOW related mods it WOULD MAKE A HUGE DIFFERANCE... well civics DON'T run all that rich so they DONT really add power i have yet to see I/H/E combo ALONE make that much of a differance on ANY pre 99 honda civic..
