I just removed the charcoal filter on a 2nd tundra, and found they just pop off by hand after poping off a corner with a screw driver, without even removing the lid.
I posted a write up with tons of pics of my first attempt. I was so mad when found out they pop off by hand. But I was able to get a pic showing all 7 layers of it.
600 miles and so far no codes, 1 MPG increase (no idea how
) but 300 mile range is sweet! Butt dyno says faster all around, and its also a bit louder.
