Source: Custom Chrome
Top quality, made in U.S.A. black or chrome spin-on filters for models from 1980 thru 2003. The large filter is one inch longer-than-stock to increase the oil capacity of the system and permit the oil filter to help cool the oil. The short filter features 24 square inches more pleated filter paper than comparable filters, and an anti-drain back valve not found on most other filters.
