    Item listed as fast shipping. Only a label was created the day after I purchased, the item didn't actually arrive to the carrier for 6 days, did not get a response to message about shipping. Product arrived not overpacked, only in a plastic bag, several boxes were damaged, but the filters themselves made it intact. Would buy from again but would communicate with seller before purchase.

    Great second choice.

    Dense is best for Japanese vehicles, but this is a close second. I chose this based on quality and price. 6 months in no problems and none expected. I only use name brand electronics.

  • Lexus ES300 A/F Sensor

    I was hesitant to purchase the sensor through the mail, thinking I would have no efficient means to return if the product ffailed. It worked great, My "Check Engine" light has not come back on in over 300 miles. Hoping it continues to do its job. Purchase saved about $ 50 versus buying from a local auto supplier. One happy customer.

  • Good price and OEM part.

    It was exactly the same as the A/R Oxygen Sensor I removed, even had the blue ribbon on it and exact Toyota part number. The part was much more expensive at the dealer even after the shipping import duties. Would buy again if need be.

  • original and perfect fit.

    Although the unit didn't come with anti seize compound, but I noticed it was already applied to the threads of it. also it didn't come in its original Denso box. However, the part was installed and so far it is working fine. It is like original part.

  • Solved the issue and was a great price plus quick shipping.

    Found a video on line which made it pretty easy to replace.
