Catalytic Converter for Hyundai Santa Fe (2013-2018) 3.3L

Direct-Fit Dual Catalytic Converter Set for 2013-2018 Hyundai Santa Fe

What it Does: Restores exhaust scavenging efficiency and resolves emissions trouble codes by replacing degraded factory manifold converters on both cylinder banks.

The Stock Santa Fe Catalyst Degradation

Subjected to severe thermal cycling within tight engine bay tolerances, the factory manifold-mounted catalytic monoliths on the 3.3L Lambda II engine are prone to washcoat sintering, substrate breakdown, and carbon clogging. This restriction increases exhaust backpressure, chokes volumetric efficiency, drops fuel economy, and triggers persistent P0420/P0430 diagnostic trouble codes.

The Engineering Solution

Engineered with corrosion-resistant 409 stainless steel tubing and high-durability ceramic honeycomb substrates, this dual converter set restores factory flow rates and tailpipe emission thresholds. Both the radiator-side and firewall-side assemblies feature robotic seam welds, heavy-duty thick-gauge mounting flanges to resist thermal warping, integrated O2 sensor bungs, and supplied installation hardware for a direct, leak-free bolt-on fitment without custom cutting.
