I can't tell if it's truly a crack, or if it's just some sticky residue with dirt on it.
Yeah, we need a close up picture.Does not look like a crack to me .
Something that severe , surly would not have made it out of a repair shop.
Where's the stock radiator cover? That supposed crack doesn't look right to me. I'd find out exactly what it is, and if indeed it is a crack then whoever did the repair work on a that wrecked car should be out of a job.
Someone probably put Armorall on it. That's how mine used to look when I used that cheap stuff for plastic parts. Uneven coat that's still wet.Also, has the boot on the CAI right before the Throttle body look like it's been scratched all up or sanded for some reason? Doesn't look smooth but I can't zoom in to verify.
