After searching for hours, I achieved the general idea of how to do this mod, with help of a few pictures that were hard to find. Yet I did not see a simple step by step guide WITH pictures. Hopefully this will help someone like me, that likes having a complete Idea of what they are getting themselves into.


Materials:
Dremel or drill with cutoff disc, or even a hacksaw
Sharpie, or chalk to mark the cut lines
7mm socket or wrench
15 minutes of time
*Recommend K&N Filters

Step 1:
Remove the Air Filters and Air boxes with the 7mm wrench



Step 2:
Remove the two plastic "baffle" peices under the filters. They should say something like "replace with AC Filter"

Step 3:
Draw a line then cut around the plastic. Leave enough of a lip to clamp your ram air hose/ducting if you decide to go this route.



Step 4:
Do the same to the other side. After both sides are cut, file down the sharp edges.



Finished product.





Results without the Ram Air Ducting:

To start off, I left the stock air filters in there, which seem to be very restrictive. (I plan on getting some K&N filters this afternoon) I was able to feel and hear a noticeable difference in power, however it didnt turn my 305 into a racecar. The engine definitley pulls harder throughout the whole RPM band. You can feel and actually hear the difference. I would guess the mod adds maybe 3-7hp. Not bad for a free mod that takes less than half an hour to do. I strongly feel as if the ram air part to this mod will "wake up" the whole intake, again I still don't expect it to be an 8sec car.


I will be doing the ram air part to this mod this afternoon, and I will edit and post that DIY then.

Hey thanks for sharing this, I've done the same thing. Keen to know how the ram air ducting turned out?

 

I forgot about this thread. I posted the pictures above as place holders and forgot to go back and upload higher quality pictures with more information.

I later installed K&N filters and made a ram air setup out of PVC pipe. I ran PVC pipe from the snorkel to the plastic housing behind the fog lights. I custom cut some metal sheets to make a cone that attached the PVC pipe to plastic behind the grille. This way all of the air that hits the grille goes straight into the intake. I then sealed all of the edges with silicone.

This setup works great. Especially over 45mph. It was well worth the time and effort that went into fabricating and installing it.

 

what about makeing tubes that go down and pull air from behind the foglights and really get a ram air

 

I have a set up from radom tech. about the same for sale look under ram air pic.
