In the case of dependability, car buyers can't do better than a Lexus, a solid producer of enduring and trustworthy automobiles. Lexus is a well-regarded manufacturer of first class, precision engineered machine that feature quick acceleration and majestic drive feel. Is it smart to expend a big payment on a fine, stylish luxury vehicle, and then be a skinflint with new OEM or aftermarket parts and accessories? To keep the value and appearance you selected with your Lexus RX300, it's important to use only the most reliable high-performance parts. Comfort-focused sedans such as the well-appointed Lexus RX300 were meant to be made use of with care and also given proper repairs. That Lexus in the garage was manufactured with the highest quality and craftsmanship; it deserves new components with a similar top level of value. Whenever your vehicle's ratio of fuel to air is not adequate, reduced combustion will be the result; in addition, a too-rich mixture causes harm to your motor and unwanted unburned fuel from your car or truck's tailpipe. The Lexus RX300 Air Fuel Ratio Sensor works at its best when it functions in all vehicles on average even though your car will run without it. The Lexus RX300 Air Fuel Ratio Sensor tracks the air and fuel levels in your engine, keeping them balanced for good operation. Your vehicle is an investment because it has great performance and great style, so to have it humming in top condition you'll need the acme in quality parts. You chose a high-performance vehicle because it had high-end engine power and performance, back up your decision and install first rate new parts. Sometimes the most difficult thing about maintaining a car or truck is finding an honest source for reliable parts. Guard your vehicle by accepting only the best aftermarket accessories .... the only kind we stock. For the most satisfaction out of your car or truck, remember that great parts create outstanding performance - PartsGeek.com has the parts you need.

2002 Lexus RX300 Air Fuel Ratio Sensor

Very Satisfied
Reviewer: John Nec

If you need this a/r sensor it is a perfect fit. Bank1 Sensor1 If you are changing this part and find it difficult to pull the old connector off you are doing it wrong. Stand on the right side of the engine your right hand can grab the connector housing your left hand can slip in between a small space on the left side of the engine to hold the old connector. With your right hand there is a small plastic tab on the housing lift this up whilst pulling the connector with your left hand, it slip right off.Mind you if your in the right position for this your chest is bent over touching the engine and your arms are fully extended in front of you. you wont be able to visually see your hands so you have to know what you are holding before you set up. i am just shy of six feet with short arms just to give you a reference point to wether you be able to to do it like this. once the connector is off you have to jack up the car to get to the sensor. Your on your own here.
