I just bought 2 O2 sensors from the dealer for my 95 Camaro Z28. The car has 190,000 miles on it and the sensors have never been changed, so I figured it may be a good idea! Anyways, I climbed under the car and noticed these don't look too easy to get to. Just wondering if anyone has any tips to help me out!? I'll be attempting this tomorrow. Also, do you need any special tools?

Thanks in advance!

 

O2 sensor sockets are helpful. One with a hex end for use with a wrench on it is best.
