This is the procedure I used and it worked like a charm.
Tools required:
2-ft breaker bar
Several 1/2 inch extension bars (about 32" worth)
6-pt socket
Process:
Disconnect and completely remove stock airboxes. This will give you a direct straight path from the engine bay to the top bolts and improve on the amount of torque that you can directly apply by eliminating the swivel joint.
If the bolt still won't break free then it is probably cross-threaded. You can try to apply direct heat to the nut with a torch to try and expand it, this might get you a couple of turns before seizing up again once the metal temperatures equalize. Spray the bolt with water and repeat. Plan B, bigger breaker bar and sheer the bolt.
The other problem I had was with one of the stock O2 sensors. One of them came out with ease, the other was cross threaded and stripped the O2 sensor threads as it came out. $100 for a new O2 sensor on rockauto.com.
