- Undo lower underbody panel. - Great to have removed in case you drop screws
- Remove Exhaust system - you can get away with leaving it on
You want a swivel joint on your socket at times and some deep sockets. You will need a small extensions as well. Some o2 sensors you can unscrew while others it is best to just unplug.
If you are using a bms downpipe fix, read the instructions carefully on where they suggest the setting to be. You can read it wrong and set it too low. You will get a CEL like I did.
Thanks for the heads up. I had planned on everything but the valve cover. It should not be needed. I may go ahead and remove the motor mount to make the job go quicker.
