Turbo Intake Hose

[bandmmorris]

I need to replace the air intake hose between the air cleaner and turbocharger on my 2007 Monaco Camelot. It has the Cummins ISL 400 engine. Any information or advice would be appreciated.

Which section needs to be replaced?   For my coach there is a hump hose that comes off the air filter outlet that connects to a "L" hard pipe and then to a cobra head connector on the turbo inlet.

Mine is the same. Do you recall the inside diameter of the top hose. It is difficult to measure and is somewhere between 4 and 5 inches.

For my configuration, the "L" pipe is 5" ID and the turbo inlet is 4" ID.  This is what I bought for that  https://www.ebay.com/itm/185539049159

Did it stand up well to the high temperatures and did you have any concerns with the restriction in the cobra head?

I have just installed the new one.  The old one was exactly the same and OEM.  So over 16 years it had a little loss of rigidity but not much.  I had a separate issue that you can read about in this thread as to why I replaced it.  It was more PM than anything while upgrading my intake filter size.  What is the issue with your connector?  Is it a Cobra head design?

Mine is not a cobra head design. The problem is mine has a split in the end of it under the clamp and I do not want to take a chance with sucking dirty air into the turbo and engine so I am replacing it.

It sounds like this is the hose you need if it comes directly off the filter outlet.

Mine is a 90 degree hose. 

It comes off the inlet to the turbocharger.

https://www.intakehoses.com/  I changed ALL that pleated intake duct, hose. Lots of air friction going on in there. The truckers use rubber fittings and aluminum tubing. That's what i did.

The Cobra heads are designed where you do not have enough turn radius for a 90 degree.  They are basically the same with regards to air flow capability, but your choice on whether you want to stay with the 90 degree or go with the cobra head.  I know others with the 400ISL have the cobra head going to the turbo.

Also given the design, the cobra head probably provides better support of the "L" pipe and may prevent cracking at the "L" pipe connection as you describe you have.

Thought a little more about this.
