I'm going to try something similar to this with the PRM intake I ordered. This thread and Myxalpyx's thread has inspired me. I'm currently running a cheapo eBay CAI.

my current tinker project is a gd3 stock air box, 3" inlet hole cut with an elbow going down passed the frame, then I just need to add an elbow to the stock fog light housing and connect the two for a true ram air inlet.

down side is living in Seattle means lots of water sucking potential.

On the freeway it is faster too. It seems to work better the faster you go. Makes sense I guess, the more air that passes through the better. The temperature of the air will be colder too.



Totally forgot about this thread but I echo your driving impressions. I hate talking about impressions but I'm giving in this time. I've changed my setup 3x already, from testing and retesting it against stock and against just using a single ram from over the radiator. It does seem to help in feel but I can't see any data (Maf g/s, Intake air pressure, injector pulse width) to back it up. The only thing that seems to have changed significantly is my air/fuel ratio.

Stock intake air/fuel rato is 11.9/12.0:1.
Filter in box with stock air inlet air/fuel ratio: 12.4/12.5:1
Filter in box with stock air inlet and foglight air/fuel ratio: 12.7/12.8:1

So it's definitely getting leaner. Been working a lot on making sure the airbox is airtight with good success. I have one more change to the hook-up in the foglight area to make it more secure and I'll be done. Great thread!

Use some polyurethane adhesive on the elbow and the back of the funnel bit and it won't come out.. Zip ties degrade with time in that environment..

It's already back together but I used regular metal clamps that are used to hold silicone hoses on metal pipe. I had to change my setup slightly because there is a metal piece in the way in the back of the foglight, which prevents you from running a straight tube to the foglight area. Somehow, I got it to work though. That's not a bad suggestion though.
