Catalytic Converter for Infiniti G37 (2008-2013) 3.7L

Direct-Fit Stainless Catalytic Converter Pair for 2008-2013 Infiniti G37 (V36)

What it Does: This direct-fit converter pair replaces worn units on 2008-2013 V36 Infiniti G37 VQ37VHR models to restore emissions conversion and exhaust flow.

The Stock Infiniti G37 Exhaust Restriction

Over extended mileage and high-RPM heat soak, OEM converters on the V36 chassis with the VQ37VHR 3.7L V6 suffer washcoat depletion and ceramic substrate fracture. Thermal stress causes the internal brick to break loose or melt, creating severe exhaust backpressure across both cylinder banks. Once oxygen storage drops below threshold, the ECU triggers P0420/P0430 catalyst-efficiency codes and degrades engine power and efficiency.

Common Symptoms of a Failing OEM Catalytic Converter

• Check Engine Light: Triggers P0420 or P0430 codes from depleted catalyst efficiency.
• Metallic Exhaust Rattle: Audible rattling from a fractured ceramic brick inside the shell.
• Power Loss: Sluggish throttle response, elevated backpressure, and failed emissions inspections.

The Direct-Fit Stainless Catalytic Converter Solution

Constructed from corrosion-resistant stainless steel, this left and right converter pair resists thermal cracking and rust on the V36 platform. High-flow ceramic honeycomb substrates with a precious-metal washcoat convert HC, CO, and NOx emissions to meet federal OBD-II standards. Factory-style flanges, mounting brackets, and integrated O2 sensor bungs provide exact OEM bolt-on alignment between manifolds and Y-pipe without cutting or welding.

Frequently Asked Questions & Fitment Warnings

Does this fit the V36 G37?

Yes. Fits 2008-2013 Infiniti G37 models with the VQ37VHR 3.7L engine. Excludes G35 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, for catalyst failure. Restores efficiency to clear P0420/P0430 codes once exhaust leaks are eliminated. O2 sensors are not included; reuse or replace existing sensors.

Are gaskets and mounting hardware included?

Yes. Includes two flange gaskets, two ring seals, and a bolt set. Soak manifold studs with penetrating oil, torque evenly, and inspect for leaks.

The Infiniti Performance Standard

Built for the high-revving VQ37VHR, this dual-bank converter pair restores flow efficiency and crisp throttle response. Replace both banks together for balanced backpressure and reliable operation.
