    I did the keman intake mod, with some slight alterations to the parts used. Since I work at an irrigation shop this made it easy to get my hands on the parts. Instead of a standard 2" sch 40 pipe I used a 2x6 sch 80 TOE (Thread One End) Nipple<------ actual name. This gave me the ability to file down the lip that I connected to the 2" coupler to create a more even space for the air to flow. Also instead of epoxy I used flex pipe primer and glue as it will hold these parts together all the same and they have a high operating temp of 180 degrees* not that it will ever hit those temps. Side note* WTF Was ford thinking when they put all that garbage in there. I hardly notice a noise increase at all.

    ^^ I think they were just trying to make the car perform worse, anyway that's what that stuff did IMO.

    I did the full keman today, and a suggestion to anyone doing it: use a 4" to 3" Clay to PVC drain adapter. Then use flexible 3" dryer hose, it will go right through the hole in the fender, and the smooth round part at the end fits snugly into the drain pipe adapter.. I then used duct tape to seal off the dryer hose from the engine bay. I didnt use sealant on the drain pipe adapter to the air filter box, its pre-MAF so I didnt see the point. The hose clamp on the adapter seems to hold it on tight.

    Bringing a old thread back to life.... I already had a Iceman on my car when I got it so I just sawed off my air box this week to see if it made a difference. It definitely did. The sound is a little cooler. Seems like a small bit more power. The light shake in my steering wheel at idle is definitely reduced... along with the udp I put on last week the vibration in the steering wheel is 95% gone. Simply put the car just runs better. I have another stock air box and put it back on tonight to take it for a ride and there is no doubt the sawed off air box is much better. I now have a question... I have been reading that just the sawed off airbox does a little better on gas than the 4" to 3" coupler/hose into the firewall to draw more cold air. Any thoughts from anyone that's played around with both setups to see which one they preferred? If its worth the small bit of effort to do this I definitely will but if its better to just leave the sawed off airbox as is that's obviously easy enough to do as well. lol Thanks guys... I really enjoyed reading over the many posts on this forum... next project for me is jbl header to 2.25" trubendz exhaust. Also got a NGP0 and a west wings wing coming to install one day when I'm bored.

    Just leave the sawed off air box. Once you are rolling it becomes a "cold air intake."

    I ran it both ways. I also have an Iceman and I ran it with the snout cut off and with the 4" to 3" reducer and didn't feel a difference. I don't really get why there would be one. The deciding factor is how much air the TB can intake. Any opening over 3" is just a lesson in diminishing returns.
