Hey, as I was looking over my stock intake air box I noticed that the tube thats inside the airbox thatthe air enters in through, gos in about 4 inch's . To me this looks like it would restrict alot of airflow. I was thinking about taking out the air box and cutting that tube off ...or at least 3 inches or so, and then using a OE Replacement Filter by aFe or K&N or something. Does anyone have any ideas about this? Im trying to find ways to save money and get the most aout of what I have..
