![Question](https://www.evolutionm.net/forums/images/icons/icon5.gif)
We were discussing this on the show and shine forum. I recently bought an air duct and short ram air filter for my auto 05 es. The questions of water and weather getting into air filter was raised. Can I get some input on this possible issue?
Thanks
Thanks

I have the carbon fiber duct from RRM and a SRI and have never had a problem with any weather/water.. the opening is too small to hydro lock the engine really. I;ve had it for probably 2 full years now.. and have raced in pouring rain and never had a problem.

water
I have the evo style cf hood w/ the vent on the driver side and the sr intake from rrm. It doesnt sit directly behind the vent but pretty close and I have never had ne issues w/ rain.

greg is right. without large quantities of water or some means of suction (like a wide open throttle an a quantity of water) there shouldn't be an issue. when you submerge the filter the "atmospherical pressure" , in this case water pressure, is what causes it to go through the filter.

and btw my filter is behind that foglight you see driving in 23+ straight days of rain in seattle with no problems

A duct from the front to the filter will not allow any water to get to your filter. The main problem is that it will carry up to a gallon of water around with you and when it sloshes just right it'll move the tube out of place and it won't work anymore (could also pull itself out from under the car)... ask me how I know. I poked two 1/8" holes in my duct to let the water out. Still works good as ever.

So what youre saying is the carbon fiber vent from RRM will NOT do any water damage to anything in the engine bay. Where can you buy those filter covers ? And does anyone know what type of project youre looking at to get that hood vent installed in a stock hood ?

Wait- you're talking about a hood vent, not an air duct. a duct comes from under the car, that vent is a hole in the hood. I think I remember one person having that thing instaleld but I never paid attention to whether he had problems with water (I'm gonna guess not though- Greg's right about the oiled filters).

i was speaking of hood duct also... seems I can't get the lingo right, some people say air vent, duct, hood vent, whatever. The little $40 thingy RRM sells. I had someone tell me it could cost anywhere up to $300 to install at a paint shop, however that was including some other work (emblems) that I'm going to do myself. I just ordered one of the water repellant filter covers today, from like autoparts.com or somewhere, it was 25 with shipping. You can go to K&N too, but it costs more I think.
