i was wondering on which is better to have and whats the benifits on each. which is better to have a line going into your intake from your engine breather hole. or to put a little mini intake comb thing.? which has more benifits hope i explained it good enough lol. i dont no the names of either of those things. i got a b18a1. thx in advance 
like the pic is the mini intake comb,
The hose is there for a reason. The little filter dose nothing but looks. Don’t put that crap on,it’s pointless.
well that is pcv or crankcase ventalation system. when the pistons are on their upstroke, it creates pressure in the head…so the pressure is released through that hole. it is much better to have the filter there rather than that smoggy oily residue going back into the intake to be burned again. but either way your not talking about any horsepower gains or torque…so really it doesnt matter what you do. its just over time the intake becomes dirty which eventually decreases horse.
