to you filter-cutting-open crazy cool guys, could someone post a modern update to the list of which filters are twins of each other on the inside, such as Mobil 1 M1-series = K&N, etc. along with who is currently the actual manufacturer of the filter (i.e. Champion, Toyo Roki, etc.)
especially the more premium filters that BITOG-ers are likely to be interested in.
gracias
