As the stock sensing element accumulates deposits, switching latency degrades, throwing diagnostic trouble codes (such as P0138, P0158, or P2A00) and locking the \u003cstrong\u003eVQ35\u003c\/strong\u003e engine management system into inefficient rich running conditions that diminish fuel mileage and foul catalytic converters.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered for high-temperature durability, these direct-fit sensors utilize fast-acting planar ceramic zirconia elements and factory-matched internal heating circuits to achieve rapid operational closed-loop status. High-grade double-braided PTFE harness insulation prevents heat embrittlement and environmental intrusion, while pre-treated high-temperature anti-seize on the threads ensures corrosion-resistant installation without galling into the exhaust bungs. Direct OE-spec pinouts interface seamlessly with the factory harness without splicing or repinning.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e4 x Oxygen Sensors (2 Upstream Air-Fuel Ratio Sensors, 2 Downstream O2 Sensors)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2015-2019 Infiniti QX60\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e\n\u003cstrong\u003eVQ35DE \/ VQ35DD (3.5L V6)\u003c\/strong\u003e \/ \u003cstrong\u003eL50\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e265-295 hp \/ 248-270 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e\n\u003cstrong\u003e22693-1PM0A\u003c\/strong\u003e, \u003cstrong\u003e226A0-BV81A\u003c\/strong\u003e, \u003cstrong\u003e234-4985\u003c\/strong\u003e, \u003cstrong\u003e234-4986\u003c\/strong\u003e, \u003cstrong\u003e234-9148\u003c\/strong\u003e, \u003cstrong\u003e22693-9HP0A\u003c\/strong\u003e, \u003cstrong\u003e226A0-4LA1A\u003c\/strong\u003e, \u003cstrong\u003e2344985\u003c\/strong\u003e, \u003cstrong\u003e2344986\u003c\/strong\u003e, \u003cstrong\u003e2349148\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2015-2019 Infiniti QX60 Base \/ Luxe \/ Pure \/ Sensory 3.5L V6\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the L50 QX60?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2015-2019 Infiniti QX60 equipped with the \u003cstrong\u003eVQ35DE\u003c\/strong\u003e or \u003cstrong\u003eVQ35DD\u003c\/strong\u003e 3.5L V6 engine.\u003c\/p\u003e\n\n\u003ch4\u003eDo these sensors require wire splicing or harness modification?\u003c\/h4\u003e\n\u003cp\u003eNo, all four sensors are plug-and-play units with direct-fit OEM terminal connectors and correct harness lengths.\u003c\/p\u003e\n\n\u003ch3\u003eThe Infiniti Precision Standard\u003c\/h3\u003e\n\u003cp\u003eMaintain factory powertrain calibration and crisp V6 throttle response.
