At Mountain Recore we specialize in the cleaning and complete repair of Diesel Particulate Filters (DPF) and Diesel Oxidization Catalysts (DOC), and we are equipped to clean your EGR system. Regular cleaning can help extend the life of your filter. When that is no longer an option for your DPF or DOC, we are able to completely remove and replace your DPF or DOC filter. In most cases this process can be completed within an hour so you can be back on the road with minimum downtime.
