Without breaking my intake.
Been on there a minute, looks like

If you heat and pipe wrench that fitting, find a steel dowel that fits snug inside of it first. The pipe wrench will crush it if you don’t. Soak it in penetrating oil first and with heat and slow easy pressure it’ll come out.
 
I had to take an open hack saw blade and carefully cut a slit in the pipe. When it gets really close to getting all the way through, you can squish it with a pair of pliers and it will come out easily. Oh yeah, penetrating oil doesn't hurt.

You can speed up the process by using a cut off wheel or saws all for the portion of fitting that sticks out of the manifold.

I seen somewhere that someone made a socket for that, can’t remember if it was on FABO or Facebook, he made some extras and was selling them
 
Cutting or an internal plug. The problem with pipe wrenches is that they can deform it and make it "grip" tighter in the threads Even an internal pipe wrench can expand it enough to bind. If you have a MIG welder, weld a big nut or old socket to it and yank it right out
 
SOAK the threads in a high quality penetrating oil for several days FIRST ( I like SeaFoam Deep Creep). The key is DON'T rush it. Soak it several times a day for several days. Then, pick your poison. I would try the pipe wrench after letting it soak. For several days. You'll know if it's going to come out or deform if you're very careful and slow. You'll feel it try to break lose, or you'll feel the fitting try to deform. Watch it where it goes into the intake VERY closely as you try to back it out and you'll see it if it tries to turn or tries to fold in. If it tries to fold in, then is the time to make a slit in it like Steve said and go ahead and fold it in on itself. I try to leave that as a last resort on aluminum intakes, because they are pretty fragile. But go at it SLOWLY and carefully. You'll get it.
 
In place of finding a dowel, use a deep socket that fills the hole. Securing the manifold while doing it will make life more enjoyable, too.
 
Find an old socket that is a neat fit inside. Insert flush, with square drive at front. Weld or braze [ more heat the better, to break the seal ]. Let it cool down. Simply unscrew, by hand, or using socket drive if still tight.
 
Also, after you soak it for a few days with your favorite penetrating oil and grab it with a pipe wrench, use a counter-clockwise/clockwise back-and-forth motion to slowly loosen/tighten/loosen until it’s done.

I used one on that same fitting. It split my thermostst housing.. $400 of welding later it was mostly fixed. I still had to retap the threads and use copious thread sealer on the new fitting.

I would recommend welding in a socket or slitting the fitting with a blade. Almost any pipe wrench, vice grip, or channel lock will cause immense suffering.

Once mine cracked, I wound up splitting the fitting with a chisel and finishing with a saw blade, then using a punch to fold the remnants inward to remove them. Then it was off to the local weldery to get bent over.
 
Mine was a sob to get off i took a very large dia nut and slid it on and welded it and backed it out with a large breaker bar. It took about 3 times of welding it.

Combine several suggestions above and it ought to come out - soak with penetrating oil like PB or croil. Slide a socket inside to keep shape. Heat around the fitting with a map or propane torch. Work cw and ccw with a pipe wrench, it should eventually give and spin out.
 
Newer ones have slots 180 degrees apart.

I made a tool out of a large hinge (yes, a hinge), by grinding stops in the proper location so that the hinge rested in the slots.

That let me use the other side of the hinge to turn the fitting without collapsing it.

...after days of penetrating oil soaking.
