I changed engine air filter at 36k for track prep and it looked perfectly fine. probably good for another 15k easy.
Changed the cabin air filter at same time. That was very dirty. probably will change that one every year
Just note that changing engine filter is not as easy as on other cars because you have to remove the air intake ducts and have to be careful not to damage the coolant line that runs across the air box.

Of course, it won't hurt to do more often if you wish... like any other maintenance.
It won't hurt.
But why? If there are any gains to change it two or three times as often, then someone may soon come along to tell us why it's so beneficial to do so.
Until then, I'll change it when the OM (this antiquated tome which tells us what the designers and engineers want, and what will fulfill warranty requirements) says.
I had a unique event. I had to change mine at 6800 miles because I drove from Oregon to Wyoming then back again during last year’s big forest fires. Tons of smoke and ashes in the air.
The filter was filthy after just ten days of driving.
When are folks changing the engine air filter? Manual says 60,000 but is it good to change it every 15,000?

That 60,000 is km! 37,000 miles! And you're not Canadian, eh?
It depends on the environment! In a dusty environment 15,000 miles may not be excessive!

It definitely depends on the environment. I just recently changed the air filter in my daily driver, and with 61,000 km on it, it still looked almost as clean as new.
I was doing some filter testing( not dyno)on my LT1,and IMO the OE filter seemed to be poorly made....in Thailand.
I tried the K&N & BMS and stuck with the BMS.High quality,dry media.
On all my cars,I clean the AF at every OCI...usually around 5k miles.

Not sure of the quality of the OEM filter but I'm sure GM buys from the low cost supplier and one that just meets their spec!
I also noted the large type, "made in Thailand" on the OEM Grand Sport filter. I use a made in USA oiled cotton, larger filter and usually clean at ~10,000 miles to maintain max airflow. It's ecologically and economically sound as well! Using the same one I had on my September 2013 built 2014 C7 on my Grand Sport! Just cleaned before reinstalling!
I normally check my cabin filter and blow it out with compressed air on my other cars but not enough miles or time on the vette especially since they are so hard to get to. I have 2 vehicles with cabin filters and I know their purpose but I am sure the filter diminishes the air flow somewhat, older vehicles didn't have them and as far as i know no harm no foul. Thoughts on taking the cabin filter out, just asking don't go nuts on this, LOL.
First as said before, the manual says 37,500 miles. Under "normal" conditions a 15,000 mile filter removes more and finer dirt than a new filter and is actually better for the engine. The best advise is to follow GM's recommendations as long as your are not driving a an unusually dirty environment.
^^ In general, a filter will stop smaller particles as it gets dirty; up to a point that is useful. However when it results in a pressure drop it's good to catch smaller particles but not performance! As everything, it's a balance!
One reason I don't like to change air filters too often is that I feel the more often you take apart the airbox and disturb things, the more chance you'll have of introducing dirt into the engine that wouldn't have gotten in there if you'd just left things sealed up nice and tight.
