Cobra PowrFlo Air Intake RAIN COVER??
« on: December 29, 2020, 12:08:18 pm »
Contacted the company and was told, “We don’t recommend using the Cobra air filter in heavy rain.”

I don’t ride in downpours but of course you never know what you’ll get caught in on the road so was trying to get a rain cover to carry just in case.

Does anyone have this air intake and uses or knows of any cheap throw on covers for it?

You already have a cover for the powerflo version, so its not like your running a naked filter.  I have the round model that many ride naked with, and I have never heard anyone complain about rain.   But if you're just ultra-conservative, can you just turn the powerflow cover so the intake is pointing down instead of forward?.

It has the holes in the front which means all rain would hit that and wiggle its way inside and then buildup around and on the K&N filter element or maybe squeeze inside the engine? Here’s a picture.

Here is a video by K&N (who makes the air filter used in the PowerFlo) reporting on tests they have done that might interest you:

I don't remember whether water infiltration issues were tested, but I believe there really isn't a problem as the oil K&N uses would repel most water droplets hitting their filters.

You should not run your motorcycle with a naked filter in the rainy season.  One of my mates who ride the motorcycle with the naked filter keeps a shower cap in his saddlebag to cover the filter during rain.

I hope that's only when it is parked, and not while running.  A shower cap would likely overly restrict airflow to the engine.  A rain sock is different in that it still breathes while shedding most rain water -- just like the oil on a K&N filter does -- which begs the point of why then use a rain sock.
