Catalytic Converter for Kia Soul (2012-2016) 2.0L

Direct-Fit Stainless Catalytic Converter for 2012-2016 Kia Soul (AM / PS)

What it Does: This direct-fit underbody catalytic converter (part 16646) replaces the factory unit on the 2012-2016 Kia Soul (AM / PS) 2.0L Nu I4 to restore exhaust flow and convert HC, CO, and NOx.

The Stock Kia Soul Catalyst Failure

Over high mileage, thermal cycling and heat soak fracture the factory ceramic brick inside the underbody converter on the AM / PS chassis equipped with the 2.0L Nu I4 (G4NA / G4NC) engine. Upstream misfires or oil consumption foul the washcoat, reducing oxygen storage capacity and triggering P0420 or P0430 catalyst efficiency faults. Once the internal mat erodes, the loose substrate rattles inside the shell and restricts exhaust scavenging.

Common Symptoms of a Failing OEM Catalytic Converter

• Check Engine Light / DTCs: Triggers P0420 or P0430 when post-catalyst O2 readings show depleted oxygen storage.
• Metallic Exhaust Rattle: Fractured ceramic honeycomb vibrates inside the shell at idle or deceleration.
• Backpressure & Failed Emissions: Plugged substrate cells restrict exhaust flow and cause failed smog tests.

The Direct-Fit Stainless Catalytic Converter Solution

Built with a corrosion-resistant stainless steel body (8-inch length, 5-inch height) and welded pipes, this unit resists underbody thermal fatigue without cracking. Its ceramic honeycomb substrate uses an OBD-II calibrated precious-metal washcoat to convert HC, CO, and NOx cleanly. Featuring a factory 2-bolt inlet flange, hanger, slip-fit outlet, and one post-catalyst O2 sensor port, it bolts directly into the AM / PS exhaust with zero cutting or welding.

Frequently Asked Questions & Fitment Warnings

Does this fit the AM / PS Soul?

Yes. This is a direct fit for the 2012-2016 Kia Soul equipped with the 2.0L Nu I4 (G4NA / G4NC) engine (Base, +, !, EX, SX). Excludes 1.6L models; EPA federal compliant only—not CARB approved for California, New York, Colorado, or Maine.

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

Yes, if P0420 or P0430 stems from a worn converter; inspect O2 sensors and exhaust leaks too. Oxygen sensors are not included—transfer or replace them.

Are gaskets and hardware included for installation?

Yes. The kit includes the flange gasket, U-clamp, and bolts with nuts and washers; soak seized fasteners with penetrating oil and torque evenly.

The Kia Precision Standard

Engineered for the AM / PS platform, this converter maintains proper ECU backpressure and O2 response for CEL-free operation. Welded stainless construction restores quiet flow and emissions compliance.
