Replacing front o2 sensors

Background: '04 G35 APS TT on stock engine.

I've been getting some codes related to my O2 sensors for the last 6 months or so.

Finally this weekend probably replacing the 2 front O2 sensors. For a stock engine it's probably pretty straight forward but was wondering if it's very difficult to get to with TT stuffed in there. Maybe I'll have a shop do it.

Any tips or suggestions from those that have replaced them? Thanks

Good luck its tight in there

And with the heat going through those pipes you need
some force to remove those sensors and alot of liquid wrench
after the car is cool.

it is tight! I know i own about 4 different types of O2 sensor wrenches and I moded some others too. getting to those sensors is a real bear on a greddy twin kit.
