Thanks for all the information.
I have looked at one of the diesel forums for a couple hours on this subject. A lot of info pertained to modifying the existing setup by removing the fresh air box, running new pipe, installing a big honkin' air filter (BHAF). I'm not real big on modifying anything, just want to make sure I get clean air at a high volume.
If there is a higher performance drop in replacement, no modifications needed, I would be very interested. Thanks for the part number on that Far North, will look into it.
Going to pull the filter and see how it's doing at some point here shortly. Rotate it, wipe the inside of the duct. It's been in there 2-3 months now.
I have found information going both ways on the subject. People running the K&N, having the oil sent to a lab to check for particulates. The oil came back extremely clean. When properly working it seems the K&N does the job. But I would rather have something I don't have to worry about and babysit.
Thanks again for all the information.
