Part Number: 21707132
The 21707132 bypass oil filter is engineered specifically for Volvo D11, D12, and D13 diesel engines. As a secondary filtration stage, it works alongside the primary oil filter to capture ultra-fine contaminants — including carbon residue, soot particles, and microscopic metal fragments — that standard full-flow filters cannot trap.
Bypass filtration significantly reduces engine wear by continuously polishing the oil supply. Over time, this extends bearing life, reduces sludge buildup, and helps maintain consistent oil pressure — lowering your total cost of ownership and minimizing unscheduled downtime.
Direct replacement for Volvo trucks equipped with D11, D12, and D13 engines, including the VNL, VNM, VHD, and VNX model lines. Also replaces Mack part numbers 20843764 and 20845764 on Mack MP7 and MP8 platforms.
