Hi, the K&N app is really picky about year for some reason. I did the look up a while back and got 33-2645 as the 164 filter. I'm about to buy a 1989 164, but 1989 returns unknown but 1988 returns 3 filters. Nick -- to be removed from alfa, see /bin/digest-subs.cgi or email "unsubscribe alfa" to majordomo@domain.elided
