C-9Two new high efficiency engine oil filters are now available with an improved filter medium. The new high efficiency 1R-1807 Engine Oil Filter Assembly is a service replacement for the 1R-0739 Engine Oil Filter Assembly and the new high efficiency 1R-1808 Engine Oil Filter Assembly is a service replacement for the 1R-0716 Engine Oil Filter Assembly. These new spin-on oil filters were released for new production engines January 2004. These new high efficiency engine oil filters are now the preferred filters for a replacement preventive maintenance program.

Standard Engine Oil Filter     High Efficiency Engine Oil Filter    
1R-0739     1R-1807    
1R-0716     1R-1808    These new high efficiency oil filters are approved for engines in all applications that use the former standard oil filters with the exception of the 3056 and 3066 engines. These new high efficiency spin-on oil filters with the improved filter medium result in an increased capacity in contamination control. Therefore, these filters are more efficient in providing increased filtration with excellent capacity in order to retain dirt with a minimal pressure drop. These new high efficiency engine oil filters provide improved protection for HEUI injectors, pump components, the injection actuation pressure control system, and other critical engine components. Illustration 2 and 3 below illustrates the improvements in the filtration of the standard versus new filters. Illustration 4 below illustrates the improvements in the standard filter versus the new filters in order to hold dirt.
