Its easy. You need an O2 sensor wrench which is like a socket with a part cut out for the wire to go through. Remove your radiator fan and you will have plenty of room to work. Other than that not a big deal.

 

shouldn't have to remove the fan, but it would make it easier. fourthgen...your in timonium..im in cockeysville

 

im in towson. i rock

 

Well aren't we all cool.

 

All you need is a 22mm wrench.. your just unclip the wire from the plug. Then unscrew it from the header. It takes like 5 mins

 

im in harford county

 

i used a 7/8 closed wrench i think. slip the harness through the hole and turn wrench, also use some anticease compound it makes removing the thing later like butter

 

When I got my Bosch sensor it came with what looked like some sort of grease with graphite inside it, for what one will assume is coming out easier next time.

 

yep put that on the threads of the o2 and it helps remove the thing later

 

soak it with liquid wrench first
