Rear-cap combustion air intake grid?

Post by JoeyD »

A few(several years ago), someone had made a mod to their coach by relocating the combustion Air intake from behind the rear wheel, to midway up the p-side rear cap.
The intake grill was the header grill from a Jeep(YJ)?
It didn't look extremely difficult, and provided a method of ingesting engine air without getting a snoot full of road debris.
Any reference to the old article would be greatly appreciated. .
I'm also looking for the document repository of Jim Exler. Many of his great posts seem to have unavailable links.

Joey,
I'm not certain about using the header grill from a Jeep, but there have been a few postings about using common 6 inch ductwork and a floor grate to move the fresh air intake as in my picture. I've noticed that my Cat runs a lot cooler since this was done - even in the 115 degree heat we encountered in Las Vegas several years ago. I got the information from Steve and Karen Pfundtner's post regarding a kit that used to be available from Safari for that purpose. My grill is a little bit more decorative, but you can stand there and feel the air moving past your hand into it.

BTW ... A large duckbill valve allows any rain water to drain

Perfect! Perfect! That’s exactly what I was seeking.
I much prefer the ornamental grates vs the YJ cowl grate that was considering.

Attached should be the YJ cowl intake.

I used some POR paint on the deco grate I installed - nice thing about the stuff is that once it sets up, you have to grind it to do anything to it. Mine has been on for 3+ years and still looks exactly the same as when I first put it on. I drilled a drain hole in the cap piece to help disperse any water that gets into the intake, but since we don't drive in the rain I have no idea how much of a difference it makes (we are pretty much fair weather RV'ers).

Tnx, Duane. After being parked for the last ~5 years, I’m finding that we’re fair-weather navigators. ~200 miles/day, averaging 45mph(food/fuel/potty breaks/dog walks/etc). Early on, the job was getting from Source to Destination, and it started to feel like work. Now, it’s a carefree jaunt, and I enjoy the journey quite a bit more.

Does any one have a thought on where to find the 7" air intake flex line.
I haven't found anything yet in an automotive line.
Thanks, Bob

Thanks Mel,
you are right 6".
Unfortunately I only need about 5' so a 25'roll would drive the price way up.
I am thinking 6" solid drain tile would work
