I wanted to show my mistress, a 2001 Porsche Boxter -S, a little extra love this season, so in additon to new O2 sensors and an oil change, I bought some decals and strip-lights to add a little show to the go -
First, I sprayed down the O2 sensors with penetrating oil to make removal easier -
Then, while waiting for the penetrating spray to do its job, I undid the sump oil bolt
After releasing the now black (?!) oil, I changed out the filter
While still on the underside, I uethe O2 sensors and swapped them out using this great set of tube-pliers to press the tab and bull out the plug-end
I cut the ends a bit away from the edges to finish them out:
I love my toys!
