black ribbed ducting (rubber)

Is that the rubber stuff?
Probably miniscule in a naturally asperated engine (not turbo), but ribbing is probably going to be quite restrictive in the airflow due to the turbulance created. Also i have seen this stuff colapse inwards in turbo charged applications.
These comments are probably totally irrelevant without forced induction, but it thought i would throw them out there.
Polished alloy or stainless looks good. Mandrel bends and polished pipe are available off ebay fairly cheap, and if you dont have tig welding facilities, silicon joints can make life easy, even in place of the bends.
In the past i have used a combination of mandrel bent 3" stainless steel bends and pipe with silicon couplings to make up some pretty crazy intercooler plumbing. Looks good and works well. Try and go with alloy though as it is lighter and easier to work with.
Also i was talking to a guy at the nationals (dont know if he is on here) who had used cake tins to make an air box. Appeared to work well.
