    *Efficient Contaminant Blocking

    PTFE filter stops efficiency-robbing contaminants ( like soot, silicone, and grime ) from damaging the sensing element, which keeps the accuracy of the sensor and extends its lifespan.

    *Faster Response Time

    Precision zirconia element detects air-fuel changes instantly for smoother idle, sharper acceleration, and precise fuel control.

    *Optimized Engine Performance

    Maximizes fuel efficiency, reduces harmful emissions, and ensures smog test compliance.

    *Perfect Fit Your Vehicle

    Built to strict quality control standards and with 100% factory-tested to ensure stable performance. Direct replacement, just install and drive.

    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 some 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 Royal Mail will not update a tracking number until it has arrived at its destination. 
    If your item still don't arrive after a few days, let us know so we can double check for you and help solve it asap.
     
    Q3: 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.
     
    Q4: Neither side lighting up? Both sides flicker, hyper flash, or work inconsistantly.
    A:Check the light 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. Even though some bulbs are builtin resistors, they may still need a decoder.
