I've got a Grimmspeed intake on my 13 BRZ with HKS front pipe and Tanabe Concept G cat-back.

When I run the intake without the airbox lid the car actually seems more powerful (and sounds better). My intake temps (IAT) go up to the 140s (F) with the lid OFF versus ~90s with the lid ON as shown by my Torque Pro App with OBD2. I'm running the stock unmodified snorkel and stock tune.

Could I actually be making more power WITHOUT the lid and hotter intake temps or is this in my head?
