Catalytic Converter for Hyundai Tucson (2010-2015) 2.4L Front

Direct-Fit Front Manifold Catalytic Converter for 2010-2015 Hyundai Tucson (LM)

What it Does: The direct-fit front manifold catalytic converter replaces the degraded factory assembly on the 2010-2015 Hyundai Tucson to eliminate P0420 trouble codes, restore exhaust flow, and maintain federal OBD-II emissions compliance.

The Stock Hyundai Tucson Catalytic Converter Breakdown

Factory catalytic converters on the LM chassis Hyundai Tucson paired with the Theta II 2.4L engine often suffer from thermal degradation and substrate erosion over high-mileage duty cycles. Excessive engine operating temperatures, oil blow-by, or intermittent ignition misfires deteriorate the internal washcoat, causing the ceramic honeycomb to crumble or plug. This restriction severely impedes exhaust velocity, spikes manifold backpressure, causes unburned fuel odors, and triggers diagnostic trouble codes P0420 and P0430.

The Engineering Solution

This front manifold catalytic converter is engineered with a high-grade stainless steel shell that resists thermal fatigue and road-salt corrosion. Inside, a durable ceramic honeycomb substrate is loaded with precious metals to chemically scrub carbon monoxide, nitrogen oxides, and unburnt hydrocarbons into harmless carbon dioxide, nitrogen, and water vapor. Built with heavy-duty mounting flanges, factory-matched oxygen sensor bungs, and precision bracketry, this unit bolts directly to the cylinder head and downpipe with no custom fabrication required.

Frequently Asked Questions & Fitment Warnings

Does this fit the LM Tucson?

Yes, this is a direct fit for the 2010-2015 Hyundai Tucson equipped with the Theta II 2.4L engine. This part is not legal for sale, purchase, or use in California, Colorado, New York, or Maine on CARB emissions-equipped vehicles.

What mechanical issues must be corrected before installing this converter?

All active engine misfires, oil leaks, and internal coolant consumption issues must be fully repaired prior to installation to prevent contaminating or prematurely melting the new ceramic substrate.

The Hyundai Reliability Standard

Engineered for everyday crossover reliability, maintaining unobstructed manifold exhaust flow protects cylinder head temperatures and keeps the Theta II running at its intended fuel-efficiency targets.
