I've been using the Wix 51307 filter for quite some time with no problems. It has the anti drain-back valve discussed in this thread. One feature I really like about this filter is it's a bit shorter than the full length filter supplied with the kit. If anyone has concerns about the anti drain-back valve, and you shouldn't, there are filters that will fit the kit that do not have an anti drain-back valve.
