By-pass: 118 mm / (4.65″) x 1 3/8″-16 dia.

118mm family of lube assemblies features a strong, durable head and by-pass (secondary) filter. It’s designed to divert a small portion (-10%) of the system’s oil flow back to the sump or oil pan before reaching the primary filter. This secondary system captures smaller contaminants than full-flow filters. Because of the increased efficiency, this filter will be more restrictive and should be located in a separate (bypass) flow-path. On the upside, it gives you a much finer level of contamination control, keeping your oil and lube system clean.
