 Subject: Question about Cold Air Intake
IP: Logged
Message:
Hello everyone I have a question about these cold air intakes. First off this is the setup I have. I have made my own home brew cold air intake with a 9" K & N with the pvc piping. I have a 99 V6 Dakota.
I was reading a post on one of these forums about a week ago that got me wondering about water getting into the intake through the K&N filter.
I had a K&N drop in filter in my stock air box before my home brew jobby and decided to take the garden hose to it and see how much water would go through it.
I turned the hose on just slightly at first, almost like a mist and very little if any water got through. Then I got to thinking, well, what if it is raining hard, as well the rain on the road would be splashing up from the wheels and what not. So I turned the water tap on more to increase the pressure and their was afair amount of water going through the filter.
This came as a surprise to me that this much water would be going through the filter like that. I assumed the oil in the K&N filter would somehow stop the water from going through it. But I was wrong.
As well, I could not begin to recreate the vaccuum of the engine sucking all that air in through the filter. Which would only lead me to assume that there would be more water than what I had seen with what I was doing with my garden hose.
All of this leads me to the following questions. Are these K&N exposed filters really worth the possible ramifications of all that water possibly getting into your engine. What are the consequences of the water getting into the engine?
I realize that if it starts raining you could just pull over to the side of the road and wait it out. But what if it is one of those long rains that lasts for a day or longer?
If anybody had any points, suggestions, answers. I would greatly love to read em.
Thanks.

I live in S. Florida and have an open K&N filter on a 360intakez. I drove though down pours for three hours going between 45 and 70 mph up hwy 70 in S. Florida. The rain was a low pressure system (beginnings of a hurricane) that was pushing across the state. I had no problems. There was plenty of traffic that kicked up even more water from the road. My truck came with no rubber flap or any other way to prevent water or debris from coming though the grill. The rain didn't even take the oil off the filter.
Hope this helped

To do any damage to the engine, you need to have a solid slug of water enter a cylinder. The filter or inlet tube would have to be almost fully under water. Mist or even a small splash would not hurt the engine. With all the open elements and ram air hoods people are putting on virtually every car I have yet to read of a motor going. Now there are some installations where it has occured where there was a ram air setup a bumper level and deep water was run through. As long as it is under the hood, you should fine.
