Maintaining the filter on an 1800 makes it way more trouble than it's worth. I bought and installed the FIPK on my '03 RAM shortly after I bought it primarily looking for an increase in economy. I got neither better fuel mileage or increase in performance, and went back to stock filter.Very well stated.I ran a K&N filter on a ford diesel pickup that had 90,000 on it when I bought it and 185,000 when I sold it.The engine never used oil and the air intake was always clean enough to eat off of.Yes you have to maintain the filter but it performed as advertised.
I'm with you!!!!ok i got the hot sauce, and popcorn, someone bring me a 12pack i want to see this fight gettin started
...it seems to me that means it has larger pores in the media. Oiled filters work on a different principle. As dirt/dust collect, the pore size within the media reduces. They start at a maximum micron rating when properly oiled and get more restrictive as time moves forward and dirt/dust collect, yet still retaining efficiency to a point, which paper media cannot do. Because of the media design, airflow is disproportionate during this time compared to a paper filters media design and rated airflow. Paper filter media are of a fixed micron rating that is the same throughout the layers and its use. Comparing oiled fabric media to dry paper media in a lab is fruitless. Comparing a Thoroughbred Stallion to a Mule for work is just as pointless as each perform work much more specifically than a single, straightline test of comparison is capable of proving without unintentionally being biased toward one or the other.
Since the area of a paper filter is larger due to pleats than the flatter surface of the oiled filters... The test K&N filter is pleated. If there are less pleats than a paper filter I would assume it to be not by much.
