The reason open induction kits dont work is cause they pick up all the heat from the engine, if you drill holes in the box the same is gonna apply, you dont say what car you have but the 172 one is quite good as it is.
Does this include an induction kit thats been relocated? As in i got a pipercross filter on the k-tec relocation pipe all joints sealed with samco sport silocone joints and clips, it seems pretty well sealed and its made the car more resposive at lower revs.
Being relocated into the front grille as much as possible it gets a pretty good cold air feed.
Ive heard drilling the airbox is pretty bad for youre engine?
The 172 engine is very supceptable to heat (all engines are but the 172 particularly) so a cold air intake will help but may pick up more dirt so the filter needs cleaning more so if dont clean it more it reduces your power.
The most important thing about intake air is that it is cold when it gets to the valves and pistons. If you have cold air at the filter which then heats up along its run the the valves then its a waste.
Drilling the airbox is a waste IMO there may have been advantages yrs ago with poor design but not realy now adays. The ides is to get more air into the engine but if your getting warm air only then its wasted.
Any air which bypasses the filter is bad as well. The filters there for a reason it does rob some potential power as it restricts intake but removoing all the dirt from the air is more important.
