Ok, so the last few days being off work have been alittle boring so i decided to do some fiddling around with the car. Its hot ten months of the year here so i wanted to try out a cold air intake. I started with my stock airbox, as it seals air tight and withstands heat very well. When you take out the airbox it has a snorkel thing which removes easily. I then dremeled the remaining lip flat and used some fiberglass to seal up the hole. I cut a 3" hole towards the bottom and installed some 3" intake tubing from PepBoys down thru the bumper "hole" and underneath the car. What i have now is a completely air tight intake routed all the way down to the wheel well. I started it up and the suction/vaccum from the tubing is quite strong so i took an old air filter and cut out the steel mesh grid from the back. I used two pieces that are crisscrossed to prevent junk from being sucked in, but seeing that its facing backwards i dont see debris being much of a problem. I was planning on having it run to the front grill but it has way too much vaccum and i could see water being an issue. I just finished about 15 minutes ago so if anyone wants some pictures let me know and i'll post. It turned out really well.

I used the blue shop towel to show the hole, otherwise wouldnt photo well.
This is the complete setup
Bottom half installed.
Steel mesh used for below.
Next two show the snorkel that i reused by sealing the one end and putting a rubber seal on the other end to mate with mesh piece.
This is tubing outlet underneath car.

Nice work so, it looks like u gutted the insides of the orginal box and then made a new front panal out of fiberglass? Looks good I am still looking to design and build something for mine.
Nice work!

Here are some final pictures. I decided not to use the snorkel part, i just attached the end cap and secured it under the front bumper. I took it for a ride and of course it "feels" different. The sound is different and the rpm's seem to hang on longer. It feels like it has better acceleration, but that could also just be my mind compensating for all the hard work that went into it. There is still alot of suction at the end of the tubing so i know i am getting true "cold air".
looks good. I've been contemplating something like this but why run the tube all the way down there? couldn't you just run it right up to the opening underneath the airbox? also seems like that mesh may be a bit restrictive.
Well, as we all know heat rises so i figured the lower i go the cooler the air, plus in the location its in it will get some cross flow thru the bumper providing cooler fresher air especially when moving. The steel mesh was taken from the back of a used air filter, so it cant be that restrictive. Plus, as far as the intake being restrictive, the intake already allows more cfm's than the throttle body uses, so its really not an issue.

Look pretty good. It would have been nice to have had dyno numbers before and after but you should see an increase in performance.
Actually, the lower you go, the closer you get to the hot pavement, but even that's a significant improvement over sucking in hot engine compartment air (and, really, a difference in altitude of eighteen inches isn't going to make a difference). An engineer I know who works for Ford once put numbers to it; I don't remember them exactly, but there was a not insignificant difference in HP production between using hot engine-compartment air and using the relatively cool air from outside.Fla02LS said:
With your intake down that low, be very careful about driving through water. I had a car with an intake that low, and it left me wading one day.
BTW, cool mod. Betcha win lots of street races with that.
