Used to plug the oil filter when changing oil on 2013-2017 Dodge Ram Cummins 2500/3500 Heavy-Duty trucks. Threads into the filter for a secure seal so the filter can be removed from the tight space without spilling oil. T-handle makes removal and installation easier. The tool also allows the technician to pre-lube the filter before installation. *WILL WORK ON 2018 PER MW*
