just change your oil more often

 

I end up cleaning it almost every time I go 4-wheelin cause its such fine sand I play in plus the homemade ram air. Its just as important not to over oil it though. I've talked to so many guys that spend so much time just cleaning the intake sensors because the soak the living heck out of the filter with oil. That goes back to what Master Tech was saying about the diesel and it causing power issues.

 

Best way to keep water out is change the location of the filter under the hood to where the water isn't. I believe the K&N stuff about not being the best filters, and I for one really don't like all the oil crap you have to go through to clean it. I swapped it out for a cone shaped washable non-oil brand, both in the D and my off-road Jeep. The Jeep obviously gets dirt off-road, and the D gets dirt hauling the Jeep on a trailer on the dirt roads to the Jeep trail heads. I have not messed with filter oil in years.

 

I have a ram air so rain and snow gets in there. Most drains out the bottom of the air box but not all. If I plan on driving through deep water I move the ram air tube.

 

I got the oiled filter for the same reason with the ram air setup. I wonder if there would be some way to put a paper filter after the oiled filter so that you'd have the best of both worlds.
