Could someone explain as to why? I installed the HKS filter recently, obviously I didn't think much of anything would happen, just figured it would be better for my FR-S instead of the paper/cardboard filter that was in there previously. I also had some trouble figuring out I had to take off the cover of the HKS filter for it fit, install took me about 20 mins longer than it should have, I still worry I put it in wrong, lol.
