Since this filter (Fram Ultra) is guaranteed for 15K, and many push it to 20K....you can use it for two OCI's (2 x 8000=16,000).
IMO....The ULTRA might be the best long-OCI filter available and definitely the "best bang for the buck". It has double synthetic media and is metal backed, and has a 99% efficiency rating as well. Its hard to beat.
