Hi mate, you are not ever going to win these 'discussions' so let it go would be my advise, they just become a magnet for posters to have a go at being funny (me included )
At the end of the day its your car and you do with it what you like end of....... but and there is a but, if you come on here asking advise on a modification that involves in your case something as crude as drilling holes in the stock air box you will catch a bit of stick, this should just be taken on board and you should move on to the next question, dont fight it, there is no point and you will only end up getting wound up buy the banter
I would look in the for sale section as induction kits come up all the time, and you will find £100 will get you a mint second hand kit for the NA, job done
