What did you all make your homemade ram-air for IROCs with?

I thought I'd use dryer tubing, but the hardware store didn't have any that was big enough, any ideas? Also if anyone could post some pics that'd be great.

I took 2 4" dryer vent caps took out the flapper and installed them into the bottom of the air boxes.Next thing I'm going to do is run flex duct from foglight opening to dryer cap opening.

Dan,
I went to HQ in Virgnia Beach but any place like Home Depot or Lowes should have what I used. I went to the plumbing dept and found rubber sewer bellows/90deg pieces etc. I did a 90deg bend from the plenum to a piece of 3" dia PVC piping (just fit under hood and above the stock radiator hose) then where the cruise and charcoal cannister set on the driver side I did a 90 deg turn down. Then I found a plastic pass thru used in wood working shops to hook vacuum hoses up to. I drilled a 3"diam hole thru the battery tray that sets on the passenger side and connected my 90 deg rubber bellows to the plastic pass thru I bolted and sealed to the tray. Then under the car, I removed the vacuum ball for the cruise and attached my K&N cone filter. I even built a little scoop to funnel air up into the fender.
I sold this to Jon Brandt (brandtmann@aol.com) He mas still have it laying around. I since upgraded to the dual SLP cold air unit. When I drag raced I pulled the K&N off and installed dryer duct out the front of the car, making an instant cold air/ram air. I know that not using a filter is bad, but so is dragracing and I never let anyone get in front of me to kick up dirt!

What do you use to attach it to the fog light tubes and air filter housing?

The tubes are in there really snug there not attached at either end and they havent budged a bit in 2 years . The tubes are so big I doubt very much it would make any difference at all sealing them to the airbox.
