Lower Emissions Oxygen Sensor 350-34439","description":"\u003ch2\u003eWalker Prod. 350-34439 Lower Emissions\u003c\/h2\u003e\u003cp\u003eWalker Oxygen Sensors are precision made for outstanding performance and manufactured to meet and exceed all original equipment specification and test requirements. Located in the exhaust system, the oxygen sensor produces a voltage proportional to the amount of oxygen in the exhaust versus the air. This data is used to control the air-fuel mixture through PORT or TFI injectors and carburetors. Sensors are monitored or checked anywhere from 4 to 100 times per second. The air-fuel mixture is thus always moving from rich to lean averaging very close to stoichiometric (ideal) ratios. The ceramic sensor body is contained in a housing which protects it against mechanical effects and facilitates mounting. The ceramic body is made of stabilized zirconium dioxide (zirconia). Its surfaces are coated with electrodes made of a gas-permeable platinum layer. In addition, a porous ceramic coating has been applied to the side exposed to the exhaust gas. This coating prevents contamination and erosion of the electrode surfaces by combustion residue and particulates in the exhaust gases.\u003c\/p\u003e\u003ch3\u003eFeatures \u0026amp; Benefits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eImproved engine response and performance\u003c\/li\u003e\n\u003cli\u003eLower Emissions\u003c\/li\u003e\n\u003cli\u003eImproved Fuel Economy\u003c\/li\u003e\n\u003cli\u003eLonger Sensor Life\u003c\/li\u003e\n\u003cli\u003eMeets OEM Specifications\u003c\/li\u003e\n\u003cli\u003eLimited 90 day supplier warranty\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eLower Emissions\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eImproved engine response and performance\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.28 lb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e5.75 x 2.12 x 1.85 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eWalker Prod.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer Part Number\u003c\/td\u003e\n\u003ctd\u003e350-34439\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUPC\u003c\/td\u003e\n\u003ctd\u003e724620092541\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eRecommended Items\u003c\/h3\u003e\u003cp\u003eCommonly ordered accessories for this product:\u003c\/p\u003e\u003ctable class=\"related-items-table\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eItem\u003c\/th\u003e\n\u003cth\u003eBrand\u003c\/th\u003e\n\u003cth\u003eManufacturer Part Number\u003c\/th\u003e\n\u003cth\u003eDescription\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eOxygen Sensor Socket\u003c\/td\u003e\n\u003ctd\u003ePerform Tool\u003c\/td\u003e\n\u003ctd\u003eW1267\u003c\/td\u003e\n\u003ctd\u003eOxygen sensor socket\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOxygen Sensor Socket\u003c\/td\u003e\n\u003ctd\u003ePerform Tool\u003c\/td\u003e\n\u003ctd\u003eW84008\u003c\/td\u003e\n\u003ctd\u003eOxygen sensor socket\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003cstyle\u003e\n.product-faq { margin: 2rem 0; }\n.product-faq__title { font-size: 1.25rem; margin-bottom: 1rem; }\n.faq-item { border: 1px solid #ddd; border-radius: 4px; margin-bottom: 0.5rem; }\n.faq-item__question { padding: 0.75rem 1rem; font-weight: 600; cursor: pointer; }\n.faq-item__answer { padding: 0 1rem 0.75rem; }\ndetails.faq-item \u003e summary { list-style: none; }\ndetails.faq-item \u003e summary::-webkit-details-marker { display: none; }\n.related-items-table { width: 100%; border-collapse: collapse; margin: 1rem 0; }\n.related-items-table th, .related-items-table td { border: 1px solid #ddd; padding: 0.5rem; text-align: left; vertical-align: top; }\n.related-items-table th { background: #f7f7f7; }\n\u003c\/style\u003e\u003csection class=\"product-faq\" aria-label=\"Frequently asked questions\"\u003e\u003ch2 class=\"product-faq__title\"\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdetails class=\"faq-item\"\u003e\u003csummary class=\"faq-item__question\"\u003eHow do I verify fitment before ordering?\u003c\/summary\u003e\u003cdiv class=\"faq-item__answer\"\u003e\u003cp\u003eCompare manufacturer part number 350-34439 against your existing part and your vehicle or equipment.
