I think it will be easiest to take the stock top of the airbox...cut a hole in the top for the pipe to go through...and use the stock clips to clip the top on to protect from heat coming over the top...when I get time I will look into it...right now I am happy my car is running smoothly again... I have been dormant in the forums so long which just means my car has been running smoothly and I had no issues....it just takes a CEL to go away and a cool new intake thingy for fun to get me excited about the TI again! __________________ 1995 318ti Active Pioneer Speakers [] Aluminum Billet door locks [] ACS Pedals/Deadrest [] ACS Shift Knob / E-Brake Handle [] Clear Corners/Tails/Sides [] Sylvania Exterior Lighting [] Custom CAI [] Dinan Engine Chip [] Dinan Transmission Chip [] H&R Race Springs [] Tokico Illumina Shocks [] BMW X-Brace [] Relocated Lighter Mod [] Custom iPod Mod http://www.cardomain.com/id/robcarync |
