hOmEmAdE cOlD-aIr

Ok this is going to look pretty hokey but it works.

I bought a snorkel from an '89 Firebird at GM ($40) cause my factory unit was short and stubby. getting this unit meant I didn't have to find a 90 degree bend and try to hook it up.

I used clothes dryer flex hose to run to the K&N in the fender well where my cone fits quite nicely and I used the original bellows turned backwards to hook it all together (had to the K&N cone has an oval opening). Like I said, pretty hokey but it all bolts together and it works. Oh yeah, previously I used a 4 inch diameter hose which worked even better but it rubbed against everything including the A/C so 3 inch is it.

another pic

For some reason I can only attach one pic at a time ? Here is a pic of the fender well area.

another home made idea

I saw a clothes dryer vent at the same Home Depot that if you turned it flat under the car it would be a natural air scoop. All I'd have to do is run another flex-hose (stuff is cheap eh ?) to the fender well from under the car and I have something like a ram-air effect -- well that would be the theory anyway. For all I know it just pics up alot of bugs and road gunk. Worth a try though eh ?

Feel any difference...? I only noticed a meaner sound, and maybe a slight increase in pedal response...however, I haven't run mine that far down (yet). Was it worth the effort?

I sure did with the 4 inch hose

I could really feel a difference when the 4 inch hose was in but this 3 inch one is reduced performance and I can feel it. Glad I am only into it (the hose) for $7.39. I think I will try to find another way to get a 4 inch hose working. The problem is on the one side the rad overflow gets in the way and on the other the rad hose gets in the way. Stuck with the 3 inch hose.

The SLP cold air uses the same fender so I figured I follow suit. I think you get more cold-air sticking the filter in the fender hole.

Mine's pretty wild like that too cept I opted for a scoop. I may have a TBI but every bit helps. I ran it from the air cleaner assembly, hijacked a hole leading to the highbeam light fed it down to the fog light area and hijacked the whole box into a scoop. I rerouted the highbeam light wire since it was long enough to another hole and it works out pretty nice. To form a seal I used weatherstripping around the hole on the air cleaner. I purchased shopvac 2 1/2 inch diameter vacuum hose to make the tubing. I have to say the shopvac material is very heat resistant and with a scoop feeding the TBI all the air it wants I left a small hole near where the thermac was to keep it roughly same air pressure as before since the idea of increased pressure is bad for TBI, not increased air flow. I'm now not air starved for the most part and have hit the 700r4 restriction of no WOT in 4th.

I've been working on an aluminum air box for my big K&N for a few weeks now. I just need to re-weld the seems and make a lid of some sorts. It's fed by a scoop that is connected to some dryer tubing(ghetto). I'll post some pics of my setup when it's done.

Have you tried going under the hoses with the 4".
I know with mine, the 3" would go under the hose that leads to the oil cooler. Not sure about 4.

Hey how are you doing ? I tried to snake the 4 inch under but it just bumped into other stuff and I had to flatten the tube to make it fit. So I switched to the 3 inch cause it doesn't bump up against the A/C unit.

This one fits ok and I am thinking I can still improve on it by making a ram-air type setup (cold air scoop under the nose) ???
