Yep, and they come with t-bolt clamps as well. COBB inlet tubes don't come with anything.
Honestly, I'd rather they come with heavy-duty band clamps (not the worm kind). Cleaner and less bulky than t-bolt clamps that aren't at all necessary on a NA engine.
Plus HPS is better quality. I've had both brands of coupler/inlet tube on other cars.

And there is a dyno graph from an '09 G37 showing some measurable gains.
Anyway, I'm done with my $0.02. Just trying to help out the OP since the COBB tubes are likely no longer available. The only other place I'd suggest checking is RallySport Direct here in Utah - they have a LOT of stuff in stock.
