[Fulltiming]

I checked the Manual for my 1992 Newell and show the same C-62891-3 Ecolite filter as the recommended filter and I concur that the Ecolite does have an extended intake port on the side in lieu of the flush side opening the filters I have used over the almost 20 years. I have used the filters I listed for three reasons: 1) that is what was on the coach when I purchased it and as I recall, that is what Newell replaced it with when I took it into them for yearly maintenance, 2) it does make it easier to access the electrical panel in the rear of the engine compartment without the protruding intake nossle, and I have had an easier time locating the filters with the curved, screened air intake at a reasonable price.

I would not be adverse to using the filter you listed. The potential advantage to the filter with the extended intake port is that in the rare situation of a runaway engine, it might be better to find a piece of plywood to put over the flat open intake port than using a folded blanket or tarp to block off the curved screened intake area on the filters I listed. Other than that, I see no advantage. Your mileage may vary.
