Comments about Denso Oxygen Sensor - Direct Fit:

I can tell you a big difference this new pre cat ox sensor improved the driveabilty of my car. Had 130k on original and it had set a light finally. Replaced and the difference has been amazing on an already decent running recently tuned engine.

      Do not know if it works, other than the Check Engine Light is off. Some people were reporting incorrect readings. I have no way to test that.
