air intake hose?? / source for cheap switches

I tried searching for this topic, but I don't even know what the thing is called. It's the 3-4" braided hose on the 3.9 engine that goes to the air intake (not raised, snorkel...the regular one).

the steel bracket has rusted, and the hose has come off the block. I'm ordering stainless ties, but what is this hose "called"? has anyone ordered a replacement that doesn't look like it's from the 1930s? As in, silicone, rubber, whatever?

ALSO. this place is in GB, and I haven't received mine, but this place has inexpensive LR switches (for aux lights, etc). They're like $6 plus shipping, which is considerably less than the $25-30 places on these shores want. Best part, they're blank, so you don't have a dome light indicator for your lockers or something;

I don't remember what its called but it goes between the plenum and the mass airflow sensor. I ordered a replacement about a year ago from Rovers North and it was very expensive, like $300. Mine had cracked and was causing the check engine light to come on. If I had to do it again, I would take it to an auto parts store and see if they have any flexible hoses of the same diameter. As long as you can bend it around the brake servo you should be fine.

Their is some very good silicon hose available as close as your local private aviation airport. I used some 3" diameter silicon hose on a Porsche 911 that I was restoring a few years ago - the factory hoses were $$$$$ so I went over to the parts counter at Epps Aviation and bought some hose there - it was orange and cost about $15 a foot at the timebut it was a whole bunch less expensive than the factory equivalent.

Mine just has a big hose clamp at each end. All I would be concerned with is if there are any holes in the tube and make sure it is snug at both ends. Don't hesitate to trim a little off if necessary--it is not rocket science and it's length is definetly not critical. I would even consider painting the outside of it with some sort of high temperature epoxy or sealant if there any little holes. Don't waste money replacing it.

95 style is plastic.

Does not look old like the 94 style.

Make sure it is held up! If it sags too low the exhaust will burn a hole in the hose!

Anyone have a source for this hose? I've been looking, most silicone hose is fiberglass reinforced, and thus is pretty rigid....I figured I could use a totally flexible one...am I wron? ordering it in rigid form makes for a lot more angle measurements...

I just got some for my snorke at a local hose shop--was $6.50/ft and is temp resis. to about 300 degrees (mine is blue). It is flexible. There was a link to a good hose shop online under one of the newer snorkel threads--

That says to +325 F.... would the one that goes to +550 F be enough? that's the highest rating I've found so far.

Something tells me any one of these will be better (performance wise) than the stock braided hose... is this correct?

The Exhaust gets real hot! maybe over 600*F at the cats. But the hose I bought slowly started sagging until it was only a few inches from hitting the headder then it melted. What you need to make sure is that it is stiff, so it stays out of harms way.

This stuff looks like it is real good but I bet it's $$$

Just checked it's $15 a foot but you would never have to replace it!

This is the stuff I used to connect the heat exchangers to the bodywork on my Porsche 911 years ago - http://www.ducting.com/GS.html -its a double thickness wire reinforced silicon hose - good for low positive and low negative pressures.
