How many of you run oiled filters in your home furnace? The oiled filter biggest problem is they tend to foul out MAFs. I just don't see the advantage of taking the chance on fouling the sensors out when there isn't that big of an advantage power wise. I have used the full cone filter from K&N before and there isn't any noticeable difference in power or anything. Just that the K&N costs a lot more and seems to be more hassle to clean than dropping in a new paper filter.

 

The type of environment a person drives in will determine how often the filter should be changed... Dusty landscapes will require more frequent changes than an area that is devoid of this issue. Check it when you change your oil, you will know.

 

they are dyno proven to have a minimum 5 hp gain. and what is a hassle when your a modder? nothing really. plus it looks kick **** in there versus a stock filter
