Customer Testimonials

“…the converter and DPF filter fit perfectly; the truck is running better than it ever has. Thank you for a great product at a great price… I would recommend DCL to anyone that needs DPF filters or converters, they are a great company.”

“DCL manufactures a quality aftermarket product that is a direct-fit with simple cross-reference to the OEM DPF part numbers. We clean our own DPF’s and DCL provides a cost effective alternative. This enables us to buy spare units that are brand new with no need to worry about where the DPF has been like some of the OEM used or re-man products.”
