i have an evo3 o2 housing. it has one stud and one bolt where it meets the dp. of course the 02 is stripped where the bolt goes so i have to remove it and stud the other side. i am just looking for tips on removing the o2 while its still in the car.. any help appreciated as it looks pretty tight. maybe special tools that make it easier ect.
thanks

You just need an extension a swivel & a o2 sensor socket, lets not forget the ratchet. /ubbthreads/images/graemlins/grin.gif

I've pulled the dipstick tube out for easier access to the bolts. I usually use 3/8 drive deepwell 14mm and a 6 in extension for the bolts. Open end 14mm for the nut on the O2 housing. Can be done in the car.
