We have created a specialized DPF Filter / DOC / SCR Catalyst cleaning remanufacturing process specifically tailored for your diesel truck or equipment needs. Don’t let engine “limp” modes destroy your wallet. A clogged filter can split or warp over time, and it will need to be replaced with a new one, which could cost thousands of dollars. Not to mention all the poor fuel mileage bills.
