Help me plan: My first intake swap ... EVER.

I still prefer a 1/4 breaker bar/power handle with a 1/2 inch 12 point socket for that job, but I would think a short reversible gear wrench may work too.
Exactly, it doesn't matter what works as long as it does. I have a 1/2-9/16 combination box wrench that I use for almost everything. As long as it does the job who cares.
