Cracked Aluminum Intake Manifold?

Just completed my second oil change on my 2026 F-250 Tremor with the HO 6.7 and I noticed what appears to be several cracks in the aluminum intake manifold. What does everything think? The truck doesn't even have 5,000 miles on it yet, no towing, and I babied it it during break in.

Looks like casting flash from the pictures. Nothing to be worried about.

Looks like upper intake
Warranty or change to pusher intake piping ,which will not void warranty

What really concerns me is the second photo. I really does appear to be cracked, right into whatever that piece is.
