    Product Material: Stainless Steel

    Product Color: Silver

    Installation Position: Upstream, Downstream

    Packaging Weight: 423 g

    Packaging Dimensions (cm): 19 x 11 x 7

     

    Functions: 

    1. The Upstream oxygen sensor is used to Monitor Raw Exhaust Gas to Adjust Air-fuel Ratio in Real-time, i.e., it is used to Detect Whether the Exhaust Gas Exceeds the Standard.

    FAQ

    Q1: Will this bulb fit my vehicle?
    A: We can match almost any vehicle to one of our bulb sizes. eBay only lets us include partial vehicle fitments per listing, but if your vehicle does not show up on the compatibility table at the top of our listings, welcome you to contact us for free consulation before purchasing a product.
     
    Q2: My item has not arrived, what's taking so long?
    A: Sometimes items take longer than expected, especially if it’s going far or to rural area. Check with your post office to see if your item has been held up. Sometimes USPS will not update a tracking number until it has arrived at its destination. If your item still has not arrived after a few days, let us know so we can double check for you and help solve it asap.
     
    Q3: Do I need to mention the Year, Make and Model in the notes when place order?
    A: YES. Please include the Year, Make, and Model in the notes section during checkout to ensure you receive everything needed for your kit!
     
    Q4: My bulbs won't fit, help!
    A: Special bulb holder may be required. See if you can take the holder from the stock bulb. If not, let us know.
    The bulb size may be wrong, double check the item you received with the item you ordered.
    Do you have an aftermarket lighting housing? These may not be perfectly fitted for aftermarket bulbs and will require some manual modifications.
     
    Q5: Neither side lighting up? Both sides flicker, flash, or work inconsistantly.
    A:Check the headlight fuses, and then check the ballast plugs to insure correct installation. If this doesn't work, there may be a voltage problem with the vehicle. You probably just need a relay or capacitor.
     
    Q6: WARNING ABOUT POLARITY
    Unlike halogen bulbs, LED are polarity sensitive.
    BEFORE you start your LED kit installation, verify the polarity on your vehicle by simply plugging the LED bulb into your vehicle socket.
    - if your light turns on, please proceed to install both bulbs onto your vehicle.
    - if your light DOES NOT turn on, disconnect the bulb and flip the socket in order to reverse the polarity (this will not damage your vehicle electrical system in any way). Once you made sure the LED bulb turns on, please proceed to install both bulbs onto your vehicle.
    Note: There is no convention when it comes to polarity. Different car manufactures have different polarity setup, even within the car model the polarity setup on your low beams and high beams might be different.
