I only run Wix filters(air and oil) in both of my daily's so this video makes me feel good about that. That said, I run the HKS mushroom filter on my KA-T and used to run the same thing on my old SR. I knew from the beginning they aren't recommended, but both of them were given to me for free so I said screw it. I buy the $10 fake HKS filter elements off ebay and simply don't give a heck. With where it's sitting in the engine bay, I highly doubt any large debris will make it up to the filter, much less through it. I'm not worried about microscopic shit cuz race car or whatever the kids say these days. A buddy of mine ran his 2871r with no intake pipe at all for a few years and practically daily'd the car. The turbo recently shit the bed requiring a rebuild, but it had shaft play for the longest time so he knew it was coming.
