Review on 🔧 Grey Denso 234-9009 Oxygen Sensor by Marcus Zimmerly

Timely delivery, easy installation. Was familiar with dashboard icons and replaced the hardest to reach with my garage = $300+. I was asked to substitute another seat but was turned away because of $$$. It's been at least 4 years and another failed and I knew the dash icons and location, right in front of me and so easily accessible on my 2001 Lexus RX300. Took about 20 mins to install. Engine started and all warning symbols disappeared. I can mention that this is an OEM part, identical to the first one I replaced and the second one I replaced. The 1st replaced is at the rear of the engine and is more easily accessible under the car with the possible help of a 2nd pair of hands to unlock the electrical connector while unplugging it. By replacing this myself I saved at least $200, and the front position does not require the special offset connector that the rear position requires. Good luck and excellent supplier and price, better than ROCK AUTO price.
