Champion COS16

Champion COS16 is a full-flow spin-on engine oil filter. It belongs to a widely used filter format found in many older American vehicles and selected commercial or industrial applications. The filter uses a 3/4"-16 mounting thread and corresponds to the PH16 replacement family.

Application / fitment

Select the filter by vehicle catalogue, previous part number, thread, gasket diameter, canister height and bypass-valve requirement. A matching thread alone is not sufficient to confirm compatibility.

• selected Chrysler, Dodge, Plymouth and Jeep applications using the PH16/COS16 filter format
• selected Ford and Mercury applications and older listings commonly grouped as Ford/Mopar
• selected Volvo and commercial-vehicle applications using the same mounting arrangement
• selected industrial and machinery applications after verifying flow rate and bypass setting

Representative comparison numbers include FRAM PH16, WIX 51319 and selected ACDelco PF13/PF20 references. Cross-references are guidance only and the complete specification must be checked for the intended application.
