Over time, factory zirconia elements suffer from severe silicon contamination, carbon fouling, and internal heater element fatigue. Degraded sensors output sluggish voltage signals to the ECM, causing inaccurate fuel trimming, unburned hydrocarbons that overheat catalytic converters, poor fuel economy, hesitations under load, and persistent check engine lights (P0130, P0150, P0420).\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis 4-piece sensor package is engineered for direct OE drop-in replacement across both banks of the \u003cstrong\u003eZ34\u003c\/strong\u003e exhaust stream. Built with fast-acting planar ceramic sensing cores and double-layered laser-welded stainless steel protective shielding, these probes resist thermal shock, particulate fouling, and vibration degradation. Factory-matched weather-pack pigtail connectors ensure plug-and-play integration without cutting, splicing, or pinning harness wires, restoring instant closed-loop stoichiometric fuel feedback.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2x Direct-Fit Upstream Oxygen Sensors (Air\/Fuel Ratio)\u003c\/li\u003e\n  \u003cli\u003e2x Direct-Fit Downstream Oxygen 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;\"\u003e2011-2013 Nissan 370Z\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;\"\u003eVQ37VHR \/ Z34\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;\"\u003e332 hp \/ 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;\"\u003e19316342, 226931MR0A, 226933RC0A, 234-4380, 234-9135, 24781, 250-54102, 350-64083\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\u003e2011 Nissan 370Z (Base, Touring, NISMO) 3.7L V6 (VQ37VHR)\u003c\/li\u003e\n  \u003cli\u003e2012 Nissan 370Z (Base, Touring, NISMO) 3.7L V6 (VQ37VHR)\u003c\/li\u003e\n  \u003cli\u003e2013 Nissan 370Z (Base, Touring, NISMO) 3.7L V6 (VQ37VHR)\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 Z34 370Z?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2011-2013 Nissan 370Z equipped with the \u003cstrong\u003eVQ37VHR\u003c\/strong\u003e 3.7L engine across all trim configurations.\u003c\/p\u003e\n\n\u003ch4\u003eAre these sensors plug-and-play or do they require wire splicing?\u003c\/h4\u003e\n\u003cp\u003eThese sensors feature factory-spec connectors and pre-sized wiring harnesses, requiring no wire splicing, repinning, or custom brackets during installation.\u003c\/p\u003e\n\n\u003ch3\u003eThe Nissan Performance Standard\u003c\/h3\u003e\n\u003cp\u003ePreserve the high-revving throttle response and sharp power delivery of your \u003cstrong\u003eVQ37VHR\u003c\/strong\u003e engine by maintaining optimal closed-loop combustion trims across every gear.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67551325159672,"sku":"DS-ELH0WKCAD","price":71.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/o2-oxygen-sensor-upstream-downstream-for-nissan-370z-2011-2013-3-7l-1.jpg?v=1790795041","url":"https:\/\/performancechiptuning.com\/de\/products\/o2-oxygen-sensor-upstream-downstream-for-nissan-370z-2011-2013-3-7l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
