beacuase i need the idle air control, honda wants 400 for it, but it is way cheaper on ebay; but that one is for an H22a , they look slightly different, but the black plug looks the same and the location of the two holes and bolt holes also looks the same, although the pipes at the bottom of the one for the H22 is different because one is not bent, and on the h23a1 one they are both bent outwards. check it out
