I want to find a easier way to get to my bank 1 sensor 1. Can I remove plenum box. Will that be enough? Thanks. Chris. I have a 06 maxima se.

 

The easiest way to get to that sensor is to remove the wipers and the plastic underneath them, then remove all the 10mm bolts and remove the black metal plate, then you should have easy access to the sensor with a O2 sensor removal tool.
