Would drilling holes in my airbox be a good idea or a bad idea??

 

I've heard good and bad things about drilling holes in your air box. If it was me i would say don't do it... but then again i did nyroc's exaust mod., almost killed me drilling holes in my baby's exaust. But it was well worth it!!!

Well back to your question if your gonna do it i've heard of flow rights or something similar that you can open and close a little piece to regulate how much air you take in. I think it was trailburner that was talking to me about them.
