Gweedo Posted March 15, 2023 Share Posted March 15, 2023 Hello all, I installed a new air filter and in doing so I noticed the air ducting (flexible corrugated material) that connects to the air filter intake had a few holes in it. Have any of you replaced this piece? if so is it one piece that goes all the way up to the outside air intake? where did you find it? or do I need to buy a universal and cut to length. is this a PITB job? thnx Link to comment Share on other sites More sharing options...
Dr4Film Posted March 15, 2023 Share Posted March 15, 2023 I replaced the air intake hose a few years back on my previous Windsor. I ordered it from an eBay vendor. If I remember correctly it was 7 inches in diameter and I only needed a foot or so. The hose clamped onto an opening at the bottom of the air intake chamber and the other end clamped onto the intake of the air filter. Link to comment Share on other sites More sharing options...
DavidL Posted March 15, 2023 Share Posted March 15, 2023 (edited) Is the ductwork on the Intake side of the Air Filter canister or on the Outtake side? If it's on the Out side, then your Air Filter isn't doing anything as dust / dirt will enter the engine via the holes....not good. At a minimum, use Duct Tape and fix the holes before the RV gets started. Yes, this type of ducting is available by the foot. Measure the diameter and the length.

Gweedo Posted March 15, 2023 Author Share Posted March 15, 2023 the duct connects to the outside, so the so filter will filter what gets in. Okay thnx for the responses . Link to comment Share on other sites More sharing options...
Dr4Film Posted March 15, 2023 Share Posted March 15, 2023 I just looked back on my previous eBay purchase and the hose was 7 inches ID and it was called RFH hose. 1 Link to comment Share on other sites More sharing options...

The air duct could have been attached to the air intake after the tail section (?) had been attached to the walls, but before the inner walls were built. You may have to cut the existing air duct and install a connector piece. Be careful with the existing air duct. It is probably very brittle. Too much stress could tear it up toward the intake.

Dr4Film Posted March 15, 2023 Share Posted March 15, 2023 Chris Throgmartin of Talin RV has an Ambassador coach. I would ask him how to replace the air intake hose. 1 Link to comment Share on other sites More sharing options...
Paul J A Posted March 16, 2023 Share Posted March 16, 2023 (edited) I replaced that corrigated intake hose, with a lot of air friction going on in it, with Aluminum tubing and rubber fittings like the Class 8 trucks use. What a great performance enhancement. https://www.intakehoses.com/ Also changed to a AFE air filter, and a Resonator , which replaced the muffler. Here is the results shown on my Aladdin Screen. ISX 525 in a 07 Executive. *****Cruising Average.***** I cruised at 61-62 MPH. Edited March 16, 2023 by Paul A. Link to comment Share on other sites More sharing options...
Gweedo Posted March 16, 2023 Author Share Posted March 16, 2023 thnx I'll check it out when I get back, leaving in the morning for a few days. only issue I would have is there is a ben/Offset going up. Resonator on the intake? I thought was for exhaust Link to comment Share on other sites More sharing options...
Gweedo Posted March 16, 2023 Author Share Posted March 16, 2023 Oops sorry just re-read your post regarding the resonator. That’s pretty good mileage but I need to cruise at least 65 mph. I ran secret hotshots diesel extreme through a tank n my power n mileage increased. I use everyday treatment on each fill up. Link to comment Share on other sites More sharing options...

Not knowing when DEF began, do you add an additive to the fuel to add sulphur to the fuel?

That is correct, the extreme is every 6k miles. Yes I use the EDT (everyday treatment) on every fill up, boosts the Cetane up. I also use there Stiction with my oil changes. Runs awesome. I don't think DEF has any effects, but you would need to look at their wen site. I'm pretty certain it says all diesels, my buddy run the EDT in his 2022 pickup I also run it in my 2018 ram diesel and my 2021 jeep diesel. both have DEF.
