Any ever replaced a A/F sensor for IS350 bank 1 sensor 1? How hard is it to do and how long does it usually take? Any special tools needed and tips would be appreciated. Thanks

Relatively easy with the right tools. You'll want a proper length breaker bar to reach it from under the car and a slotted O2 sensor socket (OEM brand from any auto parts store). Replace with only Denso brand sensors. I've replaced all four when I installed PPE headers. The best pricing I found was on ebay.

Pretty easy.
Be patient taking the sensor itself off, as it can be stubborn even with the right tools since it's been on there for essentially the entire life of the car.
