6637 is the only way to go? intake
6637 is this only way to go for a cheap intake mod or is there anything i can do to the air box so i can keep the original look 
I heard of drilling a hole or something for more air but I don’t remember if it in the air box or the front of the truck so more air will go in to the engine compartment heard of it on a for blog the had a name for it and I can’t remember what it is
Any help appreciated guys
