#44939 yep, mine is from a 99. 99-00 y8 IM's have cold start assist, so you have to plug the 4 tiny holes on the flange to use them on non cold start assist motors.
96-98 y8 IM's don't require that extra step.

#45487 The Y8/Y5 has better low and midrange, so it's better for driving around town.

The Z6 makes better power up top, so it's better for all-out power.

The Z1 throttle opening is TINY!! I don't think you would ever mistake this manifold for a Z6.

The D16A6 is NOT OBD1. On board diagnostics didn't come into play until 1992, and Honda stopped making the A6 in 1991.

As I understand it, you have a Z6 head and you're putting it in a 5th gen Civic. In that case, get yourself a true Z6 intake manifold. It will save you a ton of headaches.
