Essential for modern engine management systems, this sensor accurately measures the oxygen content in your exhaust gases, allowing the engine control unit (ECU) to make real-time adjustments to the air-fuel mixture. This leads to cleaner emissions, improved fuel economy, and a smoother running engine. It's a critical component for maintaining peak engine health and responsiveness.\u003c\/p\u003e\n\u003cul style=\"list-style-type: disc; margin: 15px 0; padding-left: 30px;\"\u003e\n\u003cli style=\"margin-bottom: 8px; line-height: 1.6;\"\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli style=\"margin-bottom: 8px; line-height: 1.6;\"\u003e\n\u003cstrong\u003ePrecise Measurement\u003c\/strong\u003e: Delivers accurate readings of exhaust oxygen levels for optimal air-fuel ratio control.\u003c\/li\u003e\n\u003cli style=\"margin-bottom: 8px; line-height: 1.6;\"\u003e\n\u003cstrong\u003eEnhanced Fuel Economy\u003c\/strong\u003e: Enables the ECU to fine-tune fuel delivery, reducing consumption and saving you money.\u003c\/li\u003e\n\u003cli style=\"margin-bottom: 8px; line-height: 1.6;\"\u003e\n\u003cstrong\u003eReduced Emissions\u003c\/strong\u003e: Promotes cleaner combustion, helping your vessel meet environmental standards.\u003c\/li\u003e\n\u003cli style=\"margin-bottom: 8px; line-height: 1.6;\"\u003e\n\u003cstrong\u003eImproved Engine Performance\u003c\/strong\u003e: Ensures the engine operates at its most efficient point, leading to better power delivery and responsiveness.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp style=\"margin-bottom: 15px; line-height: 1.8;\"\u003eThis oxygen sensor plays a vital role in the sophisticated operation of contemporary marine engines. By providing continuous feedback to the ECU, it helps maintain the ideal stoichiometric air-fuel ratio, which is crucial for efficient combustion. A properly functioning oxygen sensor can significantly impact your boat's overall performance, making it more reliable and cost-effective to operate. Its ability to adapt to varying engine loads and conditions ensures consistent performance across different operational scenarios.\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 15px; line-height: 1.8;\"\u003eApplications for this oxygen sensor include a wide array of modern marine gasoline engines that utilize electronic fuel injection and emission control systems. Its accurate readings are fundamental to the closed-loop feedback system that governs engine operation. For boat owners seeking to maintain their engine's efficiency, reduce its environmental impact, and ensure its longevity, this oxygen sensor is an indispensable component. Regular checks and timely replacement of this sensor can prevent performance degradation and potential engine issues.\u003c\/p\u003e\u003c\/section\u003e\n  \n        \u003csection style=\"margin:20px 0\"\u003e\n            \u003ch2\u003eProduct Specifications\u003c\/h2\u003e\n            \u003ctable style=\"width:100%;border-collapse:collapse\"\u003e\n                \u003cthead\u003e\n                    \u003ctr\u003e\n                        \u003cth style=\"text-align:left;padding:8px;border-bottom:2px solid #333;background-color:#f5f5f5\"\u003eSpecification\u003c\/th\u003e\n                        \u003cth style=\"text-align:left;padding:8px;border-bottom:2px solid #333;background-color:#f5f5f5\"\u003eValue\u003c\/th\u003e\n                    \u003c\/tr\u003e\n                \u003c\/thead\u003e\n                \u003ctbody\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding:8px;border-bottom:1px solid #ddd\"\u003eMFG Number\u003c\/th\u003e\n\u003ctd style=\"padding:8px;border-bottom:1px solid #ddd\"\u003e18-32154\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding:8px;border-bottom:1px solid #ddd\"\u003eSensor Type\u003c\/th\u003e\n\u003ctd style=\"padding:8px;border-bottom:1px solid #ddd\"\u003eOxygen Sensor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding:8px;border-bottom:1px solid #ddd\"\u003eConnector Type\u003c\/th\u003e\n\u003ctd style=\"padding:8px;border-bottom:1px solid #ddd\"\u003eSpecific OEM Connector\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding:8px;border-bottom:1px solid #ddd\"\u003eThread Size\u003c\/th\u003e\n\u003ctd style=\"padding:8px;border-bottom:1px solid #ddd\"\u003eM18 x 1.5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding:8px;border-bottom:1px solid #ddd\"\u003eMaterial\u003c\/th\u003e\n\u003ctd style=\"padding:8px;border-bottom:1px solid #ddd\"\u003eCeramic, Stainless Steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding:8px;border-bottom:1px solid #ddd\"\u003eApplication\u003c\/th\u003e\n\u003ctd style=\"padding:8px;border-bottom:1px solid #ddd\"\u003eMarine Engine Exhaust\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding:8px;border-bottom:1px solid #ddd\"\u003eApproximate Weight\u003c\/th\u003e\n\u003ctd style=\"padding:8px;border-bottom:1px solid #ddd\"\u003e0.2 lbs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n            \u003c\/table\u003e\n        \u003c\/section\u003e\n        \n\u003c\/body\u003e","brand":"Sierra International","offers":[{"title":"Default Title","offer_id":46389627256994,"sku":"DM-1894004","price":71.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0696\/3170\/5250\/files\/fs_1894004_Web2.jpg?v=1765363205","url":"https:\/\/marinerswarehouse.com\/products\/i-o-engine-oil-25w40-5qt-1894004","provider":"Mariners Warehouse Shop","version":"1.0","type":"link"}
