WIX Racing Filters 51291 Heavy Duty Cartridge Lube Metal Canister Oil Filter

The WIX Racing Filters 51291 is a heavy-duty cartridge lube metal canister oil filter engineered for demanding industrial and commercial engine applications. Designed to deliver superior engine protection, this HD-class filter is ideal for Caterpillar industrial engines including the 3508, 3512, and 3516 series, as well as medium and heavy-duty trucks, farm equipment, construction machinery, and mining applications.
