Bobcat® oil filters help you achieve a full engine life and match the demand of high-performance diesel engines. Their metal filter housing is thicker than competing oil filters, which prevents failure under pressure. Plastisol securely seals the filter media into metal end caps, whereas other filters use less stable sealants, such as glue. Heavy-duty coil springs maintain the media cartridge seal under pressure. And a louvered inner line allows maximum oil flow to the engine.
