Replace your factory DOC filter with our new Pure DPF serviceable High Flow DOC. DOC filters are inevitably a replacement part and eventually fail. Our High Flow DOC's flow better than stock to help you create more power, all while looking good. These kits have the ability to be serviced and cleaned up to 10 times, which is a lot more than can be said for a forced regen from your local dealership.
