You need some sort of pipe first of all. I recommend going to an exhaust or performance shop and getting a length of 3 inch metal pipe(aluminum, stainless steel, or steel) mandrel bent. You'll need to do some measuring too. Take out your stock airbox and the rubber accordian looking tube attached to the throttle body. Now you just need to do some measurements. Also getting some sort of reducer or coupler for the throttle body to the intake pipe will be needed.
:have the pipe extend 5 inches from the throttle body and have a 47 degree mandrel bent in the tube and then 10 inches from the bend to where your filter will be.
Lastly a form of coating should be applied to the pipe to protect it from engine bay heat.
I sent mine to performancecoatings.com
for a Cermachrome coating. Cost me ~20 USD for that
Hopefully this can get the gears turning in your head. Good luck!
