Catalytic Converter for Ford Edge (2015-2018) 2.0L

Direct-Fit Stainless Catalytic Converter for 2015-2018 Ford Edge (CD539)

What it Does: This direct-fit catalytic converter bolts behind the turbocharger on 2015-2018 Ford Edge (CD539) 2.0L EcoBoost I4 models to restore exhaust flow and convert emissions.

The Stock Ford Edge Catalytic Converter Failure

Close-coupled directly to the turbocharger on the CD539 chassis, the factory converter on the 2.0L EcoBoost I4 endures extreme exhaust gas temperatures and rapid thermal cycling. Repeated heat soak or upstream misfires eventually fracture the ceramic substrate and degrade the precious-metal washcoat. Once the internal brick loosens, it restricts exhaust flow, triggering P0420 or P0430 catalyst-efficiency codes and rattling under load.

Common Symptoms of a Failing OEM Catalytic Converter

• Check Engine Light: Persistent P0420 or P0430 fault codes indicating reduced downstream catalyst efficiency.
• Metallic Exhaust Rattle: Broken ceramic honeycomb rattling inside the converter shell at idle or deceleration.
• Backpressure & Emissions: Sluggish boost response and failed federal OBD-II emissions testing.

The Direct-Fit Stainless Catalytic Converter Solution

Built to OEM dimensions, this unit uses a corrosion-resistant stainless steel shell (8-inch length, 5-inch height) housing a ceramic honeycomb substrate with a precious-metal washcoat. An integrated braided flex joint absorbs engine movement, while factory-positioned hangers, turbo-side and rear 2-bolt flanges, and pre/post O2 sensor bungs enable bolt-on installation without cutting or welding. Full OBD-II compatibility restores proper HC, CO, and NOx conversion.

Frequently Asked Questions & Fitment Warnings

Does this fit the CD539 Edge?

Yes. This is a direct fit for the 2015-2018 Ford Edge equipped with the 2.0L EcoBoost I4 engine. It does not fit 2.7L EcoBoost Sport or 3.5L V6 models, and as an EPA federal (non-CARB) unit, it is not legal for vehicles registered in California, New York, Colorado, or Maine.

Will this clear P0420/P0430 codes, and are O2 sensors included?

Yes, it clears catalyst-efficiency codes when a worn converter is at fault, though O2 sensors are not included. Transfer your existing sensors or install new ones into the two bungs, and check for exhaust leaks.

Are gaskets and mounting hardware included for installation?

Yes. A ring seal, 2-bolt flange gasket, and four bolts with nuts and washers are included. Let the exhaust cool completely, soak old fasteners with penetrating oil, and torque all joints evenly.

The Ford Precision & Durability Standard

Engineered to handle turbocharged exhaust heat on daily-driven CD539 crossovers, this converter restores factory flow and OBD-II readiness. Compare against your original assembly before installation for reliable, leak-free operation.
