I'm working on a BFI and have completed the airbox, the top cover as well as a few shielding pieces. What I'm not sure about is the "scoop". Fron looking at other threads about this, it looks like people get air from the center of the car? Looking at my car (98+ conversion), I have a hole under the headlight, next to the fog light which would seem to be the most logical opening to get air from. Is that a bad idea for some reason

 

*cough* anyone?

 

Sucking in water from a puddle or rain, comes to mind....also most people don't have that "hole"
pre 97 cars have a dif. front end
That would be why they route the intake to the front.

 

Under the headlight remove that plastic intake crap and open up the inlet that flows air into the air filter box area... Then create an air scoop, I would use plast sheeting rather then plywood that is heavier and rots over time and that extends from the bumper to up under headlight...You can install a mesh air flow screen to help keep out water and debries...That is what I did...Flows great...

Again metal sheeting is nice if you prime and paint it and will infact channel the air great however I still believe that thick plastic sheeting that you can buy at the home building supply stores (Home Depot). The plastic sheeting is used for shows or out door applications and will work the best over the long haul...Kinda like the plastic covers that come stock under the car..This will not rust or decay over time and is flexable to really channel the air...I wish I would have taken pictures of what I did...

Remember wood will rot out in less then a year and the oven channeled sheet metal will rust and or rot away within 2-3 years... I am a contractor by trade and use these materials daily....If you must use sheet metal try and prime and paint with good products for weather protection, expecially if you live in a rainy area or near the ocean....Good luck..

 

Spray it with rust-o-lium ull be good.

 

i just used laundry dryer duct tubing. Since I already have a mesh grill there, that was all I needed. No problems with water during raining seasons, no problems with dirt/debris, doesn't travel that far considering the angle upward in the tubing to go from foglight to opening where the filter is.

You can sorta make out the tubing in this pic, also you can see the type of mesh i have as well.
