Catalytic Converter for Infiniti Q60 (2014-2015) 3.7L Left & Right

Direct-Fit Left & Right Catalytic Converter Pair for 2014-2015 Infiniti Q60 (CV36)

What it Does: The direct-fit catalytic converter pair restores factory exhaust flow dynamics and emissions compliance on the 2014-2015 Infiniti Q60 by clearing diagnostic trouble codes and eliminating catalytic wash-coat degradation.

The Stock Infiniti Q60 Catalytic Substrate Degradation

On high-mileage CV36 platforms powered by the high-revving VQ37VHR engine, the factory ceramic monolith substrates undergo extreme thermal cycling and thermal shock. Over time, prolonged exposure to high exhaust gas temperatures breaks down the internal honeycomb core, causing substrate sintering, structural fracturing, and wash-coat wash-out. This thermal fatigue triggers persistent downstream P0420 and P0430 diagnostic fault codes, creates excessive exhaust backpressure, chokes cylinder scavenging at high RPM, and reduces overall engine volumetric efficiency.

The Engineering Solution

This replacement converter pair utilizes a robust stainless steel outer shell engineered to withstand road debris impacts and severe thermal expansion without seam fatigue. Internally, a dense, high-porosity ceramic honeycomb substrate loaded with precious catalytic wash-coat metals ensures efficient catalytic reduction of NOx, CO, and hydrocarbons back within stoichiometric limits. Each assembly features precision laser-cut, thick-gauge mounting flanges that match OEM exhaust header downpipes and mid-pipe connections to prevent high-temperature exhaust gas blow-by. CNC-placed oxygen sensor bungs retain factory sensor clocking, eliminating harness stretch and ensuring direct plug-and-play installation without custom fabrication.
