you could drill a small hole in your moroso intake and install a gromet, or just leave it its not a vaccum leak, just tuck it somewhere where dirt is unlikely to get in

That's the vent line for your optispark. Drill into the elbow and find a grommet that will hold it in there.

Do not just leave it open. Either put it back into the intake path where it belongs, or put a one way valve on it (available at the hardware store).

Does it matter if I drill into the elbow or drill into the cai? Does it have to be one or the other?
