The Bosch 15885 uses a wideband design rather than a traditional switching sensor, giving the engine management system more detailed information for fuel control, performance consistency, and emissions management. It is a direct-fit replacement for select Porsche 911 upstream applications and reflects Bosch’s long OE development history in modern engine management. This part cross-references URO 9A260618802 for the same application.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eIncorrect air-fuel ratio readings from a worn sensor.\u003c\/li\u003e\n\u003cli\u003eDelayed sensor response during cold start or load changes.\u003c\/li\u003e\n\u003cli\u003eRough running caused by inaccurate mixture feedback.\u003c\/li\u003e\n\u003cli\u003eReduced fuel economy linked to poor oxygen sensor performance.\u003c\/li\u003e\n\u003cli\u003eHigher emissions from degraded upstream sensor operation.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eFits 2017-2019 Porsche 911, upstream. Verify the connector shape, wire count, and threaded mounting style before installation. The sensor uses a specific-fit design, so confirm the application by part number 15885 and compare the original sensor configuration before replacement.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eBosch backs this oxygen sensor with more than five decades of OE development and supplies aftermarket sensors built to OE-proven standards. The Bosch 15885 is part of the Actual OE Oxygen Sensor line, which reflects Bosch’s focus on accurate measurement and durable construction.\u003c\/p\u003e","brand":"Bosch","offers":[{"title":"Default Title","offer_id":53706579509429,"sku":"BBHK-15885","price":153.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/BS_15885_Fro.jpg?v=1793946584","url":"https:\/\/www.partcatalog.com\/products\/bosch-15885-oxygen-sensor-upstream","provider":"PartCatalog","version":"1.0","type":"link"}
