The holes are in the area behind the headlight, so not exactly in the engine compartment. I drilled holes instead of cutting out a rectangular section so that I could tape up one(or all) if it was too loud or if I felt it hurt anything. I also have the spare airbox, so I can compare the effects of the two setups by driving each over time.

I'm gonna dyno it with the OEM airbox, then swap in the modded one, then do my exhaust.
