I did A LOT of reading today... especially on the on
LN Engineering - Performance Aircooled Cylinders, IMS Retrofit Solutions LN Engineering and related links. It looks like there is a preferred IMS Retrofit installer in Oak Forrest, IL, but I might be getting a bit ahead of myself. I'm going to try to snap some photos of my filter as well as put a magnet to the debris. I will update once I have more info!
