RK series oil filters offers optimal filtration and function.  Don’t settle for a budget filter that has poor filtration element and no by pass spring.   By pass springs allow oil to bypass and still flow in extreme cold conditions if the oil is too thick.  Budget filters do not have a spring but a metal tab that bends to allow bypass..  In most cases once the metal has bent to bypass it will not bed back to allow filtration.  Protect your mini truck investment with a quality RK filter!
