Randy, thanks..thats a good list and I used the Suzuki's listed to try to find a cross to Amsoil filters, of which I am a fan. The closest I could get is a LTF160X which is Amsoil SMF-109 filter; this is prob the same as the one listed by KN as the LT 160. However, have emailed Amsoil to see what they have to say, and will post the results.
