Hello, Anybody know what this port is on a Gen4? Any issue Capping it? Trying to install and aftermarket Air Cleaner Assembly that does not have provision for it.

Thanks!

Most (maybe all) air into motor flows through that port at idle.
And with kit ecu the valve behind it controls engine braking.
