  • First Time Fit Oxygen Sensor

    DENSO - First Time Fit Oxygen Sensor (Part No. C5010137295ND)

    Description
    Denso First Time Fit oxygen sensors are constructed of the highest quality materials available. High-quality stainless steel, porous polytetrafluoroethylene (PTFE), fluorine rubber, aluminum oxide, high-grade platinum and ceramics are used in each DENSO sensor.

    Product Features:
    • SUPERIOR DESIGN - Maximizes engine performance and fuel efficiency while reducing harmful emissions.
    • DOUBLE-PROTECTION COVER - Maintains proper unit temperature for quicker response times and protects the ceramic element against silicone and lead poisoning.
    • ALUMINUM-OXIDE TRAP LAYER - Keeps silicone and lead outside the ceramic element through DENSO's exclusive design, preventing damage to the platinum electrode.
    • STAINLESS STEEL HOUSING - Resists corrosion and contamination with a rugged, watertight body.
    • POROUS PTFE FILTER - Allows atmospheric oxygen to enter the sensor without permitting water or engine contaminants to seep into the casing. Denso First Time Fit oxygen sensors are coated with a special formulation of aluminum oxide to trap impurities outside of the ceramic element. In head-to-head testing against the leading competitors, DENSO oxygen sensors were rated two times more resistant to silicone and lead poisoning. Installation Notes: Vehicles equipped with Air Fuel Ratio Sensors may look very similar to the Oxygen Sensor. Please confirm the correct part before ordering and if the connector does not match, do not install. Recommended Installation Tool - 234-0100, O2 Sensor Socket Set

      Replaced my upstream sensor on a '99 Accord. THOUGHT it would be so simple I could borrow the socket and do it in the parking lot. While the VIDEO shows a sensor with a plug, this one has 4 bare wires and requires much more time, thought, and tools. And, on the issue of tools, the website specifically said that this socket was available for loan; the 2 people in the store looked at me blankly. I would have "purchased" the kit to return if that option had been given. I would have needed the deep well socket to avoid removing the head shield; thankfully the little rusted bolts came out. Wires for my setup were blue to white, green to white, and either black to black. Definitely make sure the included directions work for your setup before removing (and destroying) the old one.

      Buyer Beware

      Buyer Beware

      Submitted 2020-11-11

      By Kmurfone

      From St. Louis, MO

      I purchased this OEM brand O2 sensor for my 2007 Suburban and it is the downstream sensor. After opening the box, I found that that the sensor doesn't come with a plug but just bare wires with four wire crimp splices and heat shrink sleeve. Had I known this, I wouldn't have purchased this sensor. Later I found out that it is a universal type sensor so that is why it doesn't come with a plug to plug into the vehicle's wire harness. Then I noticed on Advance Auto Parts website, the "Universal" word in the sensor type. In this case, Universal, means that it won't have a plug and you'll have to splice wires together at installation, so buyer beware. I also purchased the Denso upstream sensor from Advance Auto Parts and it is a Direct Fit type which means that it has the plug and requires no wire splicing. I don't understand why Advance Auto Parts doesn't sell the downsteam sensor with the plug on the wires.
