"functionable". lolJeepinformant pulls the hood vents off a Rubicon and inspects them thoroughly. Look fake to me but you be the judge.
that hole is purely to keep water from standing in that fake hood vent. they must not have felt venting was needed. easy enough to modify it to make it functional though. will the jeep actually benefit from more heat extraction? jeep must not have found that to be the case through extensive their testing.
