Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Diesel Oxidation Catalyst 60502. With features including free-flowing mandrel-bent tubing and highly corrosion resistant stainless steel construction, easily install this converter yourself using the proper tools, no cutting or welding required. MagnaFlow’s state-of-the-art metrology department uses the latest 3D scanning systems during research and development, so you can be confident that your new part will fit and function like the original equipment. By replicating the OE design, the single laser fusion weld greatly reduces the possibility of a leak, and our compact, low-mass design also allows for greater thermal efficiency. This replacement part is designed to meet or exceed Federal emissions requirements set forth by the EPA, complying with legal standards for OBDII Federally registered vehicles with California or Federal/EPA Emission systems.

A common problem on the Duramax LLY engine is contamination of the fuel fittings resulting in injector failure when serviced. Corrosion can form between the line and injector nut and fall into the injector when the line is removed or installed. Replacing the line at time of injector replacement or service is highly recommended to reduce injector failure due to contamination.
