Operating in harsh exhaust environments directly off the twin-scroll turbocharger, aging sensors exhibit sluggish response times and false lean\/rich voltage outputs. This degradation triggers intermittent Check Engine Lights (CEL), fuel trim adaptations exceeding DME thresholds, rough cold-start idling, and compromised fuel efficiency.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered to match OEM switching speeds, this 2-piece kit provides complete pre-cat wideband regulation and post-cat catalyst monitoring. Manufactured with high-temperature planar ceramic elements, dual protective covers, and laser-welded stainless steel bodies, these direct-fit sensors resist silicone and lead contamination. Direct-plug OE-style wiring harnesses with factory-matched weatherproof connectors and pre-coated anti-seize threads ensure a gas-tight seal, eliminating wiring modifications while stabilizing stoichiometric control.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1x Upstream Oxygen Sensor\u003c\/li\u003e\n  \u003cli\u003e1x Downstream Oxygen Sensor\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;\"\u003e2014-2016 BMW 2 Series, 4 Series\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\u003eN20B20\u003c\/strong\u003e \/ \u003cstrong\u003eF22, F23, F32, F33, F36\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;\"\u003e240 hp \/ 255 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\u003e0258010418\u003c\/strong\u003e, \u003cstrong\u003e0258010419\u003c\/strong\u003e, \u003cstrong\u003e0258027029\u003c\/strong\u003e, \u003cstrong\u003e11787589121\u003c\/strong\u003e, \u003cstrong\u003e11787589122\u003c\/strong\u003e, \u003cstrong\u003e234-4562\u003c\/strong\u003e, \u003cstrong\u003e234-5054\u003c\/strong\u003e, \u003cstrong\u003e758912102\u003c\/strong\u003e, \u003cstrong\u003e758912202\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\u003e2014-2016 BMW 228i (2.0L Turbo)\u003c\/li\u003e\n  \u003cli\u003e2014-2016 BMW 428i (2.0L Turbo)\u003c\/li\u003e\n  \u003cli\u003eBMW 320i (2.0L Turbo)\u003c\/li\u003e\n  \u003cli\u003eBMW X1, X3, X4, X5, Z4 (2.0L Turbo applications)\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 F22\/F32 2 Series, 4 Series?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2014-2016 BMW 2 Series and 4 Series equipped with the 2.0L \u003cstrong\u003eN20\u003c\/strong\u003e engine. \u003cstrong\u003eConfirm your vehicle utilizes the 2.0L 4-cylinder engine prior to ordering, as 6-cylinder models (N55\/B58) use different harness lengths and pinouts.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eIs an ECU adaptation reset required after installing these sensors?\u003c\/h4\u003e\n\u003cp\u003eWhile the DME will gradually relearn short- and long-term fuel trims, clearing existing fault codes and resetting adaptation values via an OBD-II scan tool is recommended to immediately restore factory air-fuel mapping.\u003c\/p\u003e\n\n\u003ch3\u003eThe BMW Precision Standard\u003c\/h3\u003e\n\u003cp\u003eMaintain proper closed-loop lambda control and ensure clean emissions compliance without nuisance Check Engine Lights or erratic fuel trims.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67551290556664,"sku":"DS-EXY58AKDK","price":68.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/o2-oxygen-sensor-upstream-downstream-for-bmw-2-series-4-series-2014-2016-2-0l-1.jpg?v=1790794659","url":"https:\/\/performancechiptuning.com\/de\/products\/o2-oxygen-sensor-upstream-downstream-for-bmw-2-series-4-series-2014-2016-2-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
