Matt, there is a drain slot in the plastic portion of the inlet. That would drain any water running into the intake opening. I plan to goto the volvo dealer today because they ordered in a piece of stove pipe for me, they needed some for stock anyway. Also, the dealer can get me the proper part if I want to pay $175cdn for it. | ||

Side note to this. While driving in a heavy rain, would the water running down the hose right on to the belts, right read brake disk, alt hurt the car? | ||

I may have found a source for the aluminum style hose. I was looking at my airtight fireplace today and noticed a duct that runs from the fresh air inlet up to the combustion rails. It looks like what I want and the manufacturer of the fireplace is 5 minutes down the road. Ill go tomorrow. The company is wolf steel that makes napolean fireplaces. I figure they would sell me a length of it. | ||

Yes, the more cold air to the engine bay the better. | ||

It looks to me to be the same size/material as a 911 heater hose which have 2 The VW hoses are a 2" diameter and a cheaper black paper covered hose The 911 hose is a much thicker and higher quality hose and is the same brown color a porsche parts supplier such as pelicanparts.com could give you the correct dimensions, the hose costs about $15-$20 and is about 30" long | ||

Interesting, I guess they found a need when the converters were introduced, increasing engine bay temps. | ||

The cooling hose is shown in the 1978 catalog:  | ||

Just posting this as a reference for early 308 GTBs (1975 and 1976). My 1976 GTB does not have that cooling hose. This is from the 1976 308 GTP Parts Catalog:  Barry | ||

Still havent made it to the VW dealer, too busy but I will post what I find. I have a couple of other ideas as well. | ||

Paul, let us know if you find some that's affordable. $30/foot is ridiculous! | ||

Thanks Gerrit, Ill still try the VW dealer first at $30US a foot. Actually, Rocco might have some, I never thought to call him. | ||

Ferrari Parts Exchange has the correct hoses: http://www.ferraripartsexchange.com/ducthose.htm | ||

OOPS!!! re: 2-1/4" diameter hose. You want 100mm/2.5" hose. I just checked the box for the duct tubing I used. It was 2.5" ID (Makes sense: ~=100mm). It was a very snug fit. Sorry I miss-remembered the size in my earlier post. Good luck, let us know if you find anything. | ||

YJ Wranglers have a hose that should fit, aluminum over paper, I think that's what is stock anyways on the Ferrari. The Jeep uses it to vent the engine up through the airbox, but it would work. Not sure of the size, but it sounds about right. My 308 doesn't have this hose and I don't have it on the jeep anymore (got tossed when I swapped carbs, different air filter assembly) so I can't measure it to be sure. Just a thought though. | ||

Ive tried a few auto parts stores even a truck shop for this hose to no avail. The largest I have found is 2"ID and I need 2-1/4ID. I havent tried the VW dealer yet because they arent open on the weekends. That was my next stop though. Ill try tomorrow. I have found both black and silver, Im assuming I need the silver one for the correct look? | ||

It points at the inner cv boot. The camera is too big to get in there. | ||
| Paul Newman (Newman)
Member Username: Newman Post Number: 516 Registered: 12-2001 |
Thanks Matt, its still tough to see how it aims at the diff though. Does it go in behind the header or point at the inner cv boot? | ||

I would like to see a pic and I guess Ill start the hunt. If you really wanted the correct one, would the dealer still have them. Ya I know, it would probably list for $100 though. | ||

Did you ever think if you blocked that plastic tube where the alum. hose fits on it would force more air into the airbox. Better air ramming effect???? Just a thought for comment.... | ||

Paul -- (many moons ago) I got a piece of the ribbed aluminum-over-paper tubing from a mainly VW parts house that fit my ex-308 perfectly (I think it might have been associated with the air-cooled VW heater system) -- just a thought... | ||

PS. Magoo, Your right, It blowes on the diff, trans, both cats and muffler. | ||
| Matt Lemus (Mlemus)
Junior Member Username: Mlemus Post Number: 153 Registered: 8-2002 |
I'll tke a picture and post tomorrow when I get to work. Mine never connected to anything. It is a straight, rigid hose that just blows air at the diff and trans. It should be posted @ 7:00am pst | ||

The pipe is made of ribbed aluminum over paper. It's the same construction as the heat riser tube Chevvy used for years to bring exhaust manifold heat up to the automatic choke. It's rigid enough so that it's only supported by the hose clamp attaching it to the fibreglass intake plenum. It ends shortly above the inner CV joint. I've been told it's there to duct cool air into that general area so that engine/exh. manifold heat won't cook the CV joint. My car had one when I pulled it apart to do the 1st cam belt job. Unfortunately It was nowhere to be found when time came to reinstall it. I think it must have gotten into the metal recycling bin somehow(sigh). I tried to locate large heat riser tube, but the largest I could find was still way too small. I replaced it with a ~2-1/4" diameter flexable air duct tube from autozone. It's made like a plastic clothesdryer duct,only black. It's pretty flexible, but the spring inside keeps it from collapsing. I had to suspend it with a tie wrap around a hose in that general area. Think it was the re-breather hose for the air filter box. It gets the job done, but sure isn't original. GOOD LUCK IN FINDING ONE THO I'm still hoping the original piece will turn up as I called lots of places & they just laughed at me(sigh). Several places claimed there was no such part, even tho I had a F* part number. | ||

It probably acts as somewhat of a cooler for the cats also. | ||

Thanks Matt, I was also wondering how it mounted at the diff. It looks like a tight fit past the header. Post a pic or 2. | ||

Matt, A photo would be helpful. I'm also missing this pipe and would like to know what anchors the differential end. Is there a bracket? | ||
| Matt Lemus (Mlemus)
Junior Member Username: Mlemus Post Number: 151 Registered: 8-2002 |
Paul, Mine is 12 inches long and is made from what looks and feels like aluminum (sp?). It points right at the diff and attaches to the same connection for the airbox but it connects underneath that junction point. I can take a picture tomorrow if that helps m | ||

Im missing a pipe apparently, that runs from the round inlet that is part of the air intake on the right quarter. It is around 2-1/2" in diameter and aims down on an angle. I was told it is for cooling the diff. What does this pipe look like and how does it mount? The car is a 79 carb 308. |
